Anybody out there replaced their stock Gen 3 heads w/ Strikers or Greg Goods w/ or w/out cam as their only mod? I see Striker claiming a 100 hp gain w/ their heads and cam, my Viper tech says NO WAY! My tech says a 60 hp gain is more likely and he is right 99.99% of the time...any advice guys?

Are there any known differences between Greg Good heads and Striker heads? From a performance and/or quality perspective? Also, the 08 heads will fit the Gen 3 Vipers, anyone planning to swap to the Gen 4 heads?

Strykers are available for he GenIII. Without changing cams, there isn't much value in doing heads. and incrementally, the work isn't that much more when you have the heads off.

Greg Good does incredible work on a stock casting. for 2x+ the money, you can have stryker heads.

But the car that ran 7.98 @183 (or was it 181?) was using STOCK castings! So a lot of it has to do with $$$. as you need to spend the full 7k for the heads+rockers w/ the Strykers. Greg Good is a phenomenal choice if you don't want to drop the $$$ on the strykers.

Strykers have better cooling if you are forced induction. If I were doing it all again and not going crazy TT i'd just stick with the greg good heads. And I did for a looooooong time until I wanted to up the power to stupid-crazy levels. then i went with strykers.

good luck!

There are some 700rwhp vipers that are N/A. But they are higher compression, bigger heads, bigger cam, and some are stroked/bored.

And who does those kinds of mods? I know Racing Solutions used to do it, but they never return my calls or emails. Who is the go-to company for bigger heads, cam, boring, etc?

666rwhp on a NA motor would absolutly crush a my Paxton Viper putting out the same HP. Becuase you'd get much more HP and torque down low and a much better and higher power band.

If I had to do it over again, I would have spent the Paxton Money on Heads, Cam, Headers, Vec3, and whatever else I could have gotten. :) The car would have performed better and more consistantly on hot/humid days.

Wow! That is very interesting! I do understand that the cost to rebuild the motor to get 666 rwhp can be very high compared to the Paxton, but it might be worth it. Who would you use to build you a 666 rwhp n/a motor? I see some really good numbers from one particular tuner's site that is not very popular w/ members here, who does reputable work?

Exotic Engine,

Call Kevin Singleton. 951-545-8223. Kevin builds race engines for European Viper owners and many others. He also builds some mean street stuff.

He built my 535 ci Paxton motor. It made 700 hp / 700+ tq N/A on the engine dyno with a low 9.6 to 1 compression ratio and a blower cam. If we would have gone N/A and installed a bigger N/A type cam and more compression, we could have been closer to 800 hp at the flywheel.

I'm not sure who I would have went through. However, you wouldn't need 666rwhp na to beat a 666rwhp paxton. I think 600rwhp NA would be one mean machine.

Wouldn't have the added weight of the Blower, plus could make the redline much higher. I'm not sure if you'd even have to go into the bottom end to get there. Figure 450rwhp stock + Heads/Cam/Headers and a good tune would have to get you darn close to 600rwhp. Then spend the extra money you saved get some Sidewinder rims w/ PS2's.

This is the way to go!! I would prefer to get 800 hp (696 rwhp) and get used to the car and see how it helps improve my driving experience and shuts down all reasonable competition while keeping a relatively sane car. For all you guys that are modded, hell, 505 rwhp is still sick power for the streets, at least in CT. 750 rwhp is overkill or a death sentence up here in the congested streets of the North East! I have held my own in my few street fights (07 Porsche Turbo gave me fits but I protected the snakes honor) w/ my estimated 580 flywheel hp. I am sure I can demolish almost all except fellow Vipers that have crossed over to the dark side:D w/ 800 flywheel hp!

I too was looking for options to get around 600rwhp street car. I'm quite amazed how much horsepower can be gaied from heads+cam+header+vec3. If 600rwhp in NA can be done in 10K range, I would've never considered paxton route. Is there any reliability issue with NA set up? Any recommended NA engine builder in So Cal?

How much weight savings are achieved w/ Sidewinders?

Everyone is telling me to go to Pro Line racing, they actually build engines for other reputable tuners. I think you WILL have reliability issues if the wrong builder builds your engine, I have read about that too. There is a builder/tuner named after a cognac that has built some n/a engines w/ known problems, at least that is what I have read. I am calling Pro Line Racing for my engine work.

I will second the recommendation of Exotic Engine. Kevin Singleton built my engine. DC Performance did the tuning.

(I've never even heard of Pro Line Racing. Who is "everyone" that is telling you to go to them? Does "everyone" actually have n/a Viper engines built by these guys?)

My engine is 609 hp and 609 lb-ft at the wheels. It is not a stroker motor (stock stroke) and only has a slight bore increase (4.125")
I could have had more power out of it, but kept it on the conservative side.

100 hp gain with heads and cam is EASILY obtainable. Any viper tech who says you can't gain 100hp with heads and cam doesn't know what he's talking about.

Beware, however. When you start adding power, you are eventually going to have to start upgrading other components (clutch, half shafts, transmission, etc.) to handle the extra power.

Proline (www.prolineraceengines.com) is the place that does several of the viper tuner's engines. They are in GA and do a heck of a job for a more than fair price.

Add to Kai's list of upgrades: Fuel. need more and bigger rails first. That's one of the first things that needs to be upgraded!

Well, since I broke my Viper today I guess it would be a good time to get the engine work done. During some very spirited driving I sprung an oil leak and possibly did some engine damage. I had it flatbedded to Tators. I might as well have the engine work done now...hell, now I have an excuse to spend the xtra cash to get my 670 or so rwhp!

That's how my engine mods started. I blew my engine and decided that I could rebuild it . . . faster . . . stronger. I'm not to $6 million yet, but it sometimes seems that way.

Sorry to hear about your breakage. Hopefully it can be repaired under warranty.

But for the short term, you can change your signature to 0 est rwhp. :p

I posted about my weight savings on rims and tires awhile back, but going from 5 spokes that came on my car stock to sidewinders and PS2's I shaved right at 70lbs.

I will say I get less traction now then I did with Runflats though. Much less weight for my car to move and it's easier for it to break traction. However daily driving has become a breeze. I can cruise down the bumpiest roads and hold my steeringwheel with one finger(if I wanted to) vs. Two full hands before. The car is much more predictable and way easier to control if you want to give it some gas on a turn. Really can't say enough about how much better this combo was on my car. Only down side is traction at WOT on the street. 40mph in 1st gear and it will break traction.

Have only gotten to take the car to the strip one time since adding the new rims/tires and can tell you I gained quite a bit. I left tire pressures the same(35#s) as my runflats so i could get a good idea of what the tires were doing for me. I cut consistant 1.9's vs my previous 2.0's. And my MPH was the same even though it was 10 degrees warmer, much more humid and pressure was down.

Kai, we both have 04 SRT's, I was shocked that I sprung an oil leak under basically normal "hard driving". I am not sure of the damage yet, but Tator will let me know soon. How did you blow your engine and what exactly was damaged? And, how will you prevent doing that again?

I was at an open track day. Lost the #3 rod bearing due to oil starvation. Started a cascade of bad events culminating in a blown engine. (You can check my member gallery for pictures of shattered rods, pistons, damaged block, etc.) I had a comp coupe oil pan on the car at the time.

I've added an accusump to help address the oiling issues. My crankshaft is also designed for better oiling, and I have coated bearings as well. When the 2008 oiling system becomes available, I will buy one and put it on my car.

One of the SRT Ram guys had Joe Donovan do a heads and cam package on his truck.

Baseline numbers were 467 rwhp and 515 rwtrq
After: 535 rwhp and 566 rwtq-CORRECTED (549rwhp/580rwtq STD)

By 3500 rpms it is already making over 500 ft pounds of torque and it stays over 500 ft pounds all the way over 5500 rpms.

This was Joes first attempt at a package like this for the truck. He would need to do something a little different for the Viper given its weight difference.

Exotic Engine is also doing some monster builds on some turbo SRT Rams.
