An increase of 70 WITH the heads. Or go with Strikers and gain considerably more than that...:)
Or go with a turbo setup AFTER you build the short block...
Cool; yes Jeff does a great job porting HIS OWN DESIGN heads..;)
Those heads do work really well...
Great shots of your car...I'm generally not a fan of the black wheel thing, but they really suit yours and look great!

Factoring in the minimum 400 pound difference between the 2 trucks (Reg. Cab vs. a Quad Cab), your numbers are correct based on both trap speeds and on r.w.h.p. comparisons, and equate to a 50 horsepower difference. As in Post # 111 above- there is an approx. 50 horsepower difference between...
Yes, that is correct; it is the same individual who designed the Strikers and the Gen IV heads. So basically he saw limitations with the Gen IIIs, and came up with the Strikers. And when the Vipers were no longer competitive with the new Vettes, the Gen IV heads were created (which are very...
Yes, that is correct sir and I am not really surprised that you question the results. It's all good...
Engine power is all about breathing and primarily the heads/induction systems.
The problem here is that often MANY components are changed all at the same time during a build and it becomes...
A gain 10 and 10 @ 5000 with a loss of torque in the 3000 r.p.m. range; As tested by DC Performance with a extrude honed intake by Form & Function and a divider behind the t. body.
Used with an o.e.m. unported set of heads...
Hi,
Lots of talk about dynos here. In the end they are a tuning tool. Dynojets are typically 10% higher (around here), than Mustangs or a Dyno Dynamics dyno, like we use. So regardless of what a given dyno spits out, I use the numbers to check if a mod helped or hurt.
And as mentioned, dyno...
Hi Greg,
I am more than familiar with the various lifter designs and how they operate and I am not disputing the necessity of a solid in a BIG power/HIGH r.p.m. application. It used to be far more of an issue before hydraulic rollers came out because H.R.s can follow some fairly high velocity...
Solids??....hmmmm. The idea of the high bleed-down o.e.m. hydraulic lifters IS to make the cam appear smaller (and of course to pass emissions) and give the engine mild street manners. So, how big are the hydraulic cams being used that need to be changed to solids to give them "better street...
So now they are giving the crank even more oil on the Gen IVs with their new bearing design... I didn't know that the mains were in any danger of starvation on the Gen IIIs..:dunno:
Ronnie
Greg Good-
Thanks for the info. There are very few people willing to share good information and that is unfortunate.
In a hundred years, none of this will matter...:)
1BAD- That's right, dynos are tuning tools for before and after results and a great place to see if an engine is...
There are zero driveability issues except you can blaze the tires at will. :) I went with a small custom grind cam (226 @.050 with a wide LSA) to build torque in my truck (607 wheel). It still has a slight lope at idle however. The Striker heads use a fast-burn combustion chamber so you can...
Great talking to you. I was shoveling snow (-15 here) so the drag radials aren't doing much good today. ;) The track (such as it is) reopens here in May at the earliest, so there are long periods to get ready for the short racing season.
The Striker Head and Custom Cam packages have been working...
No surprises on my end- Yeah, "Blown" is right..
There seems to be a misconception out there, that there is a weakness in the cast o.e.m. Gen III pistons that won't allow them to stand up to the increased "power" imposed by the superchargers. That isn't the case at all, from what I have found...
Yes, I saw the year(s) that your car was doing what it was doing and ten years ago; it was a fast car, period.
It's sad to see them when they aren't getting a fair chance. 2008 in Vegas for their Mopar Viper deal, there were a string of Vipers running 13s...
Most of the stock 2008s we see dyno...
I thought it should be close. ;) I do all of my own work and I'm involved with some pretty high horsepower stuff up here in Calgary. The truck was more of an experiment than anything else...
Your time is a 10.5 @ 132 on a sea-level pass. That's rockin!!
The cam I have in the truck is a one-off...
No problem. The guys in the "grocery getter" Quad Cabs get fun poked at them quite often!!
Anyway, the original intent of my post was to provide information as to what a cam and head package could do for a naturally aspirated engine...(even in a heavy truck). Add another 30 wheel to my numbers...
Agreed; the current Regular Cab record is actually 12.024 but my 12.53 is the current world record for a Naturally Aspirated Quad Cab without power adders of any kind. There is a distinction between the trucks on the forums.

Hi.
This is my first post here but I am not new to the Viper engines. Without head work, a cam change won't net you much horsepower (15'-ish) as the heads and cam are already a pretty close match. The o.e.m. heads don't flow much past the .544 lift of the o.e.m. cam anyway. It is a fair bit of...
