I don't see a problem. Assuming you are losing 10/10 with the rear and your heads You would be at 360 unlocked with a 10 bolt and 241s. Sounds on par with me.

Pull your pushrods and check to see if you have a bent one...then get some hardened ones.
I replaced the pushrods for comp cams chromoly 7.4s and not one of the stock pushrods were bent. while i was in there i replaced the rockers with other stock rockers with the trunion upgrade.Thanks to djfury05 for the hook up on all of the parts needed.

I've done a bit of research over the past week or so into that cam, and I see numerous people that seem to dyno like a bolt on car with it. I know, yea "the dyno's a tuning tool, take it to the track" and I'm a firm believer in that myself. I still don't think it should be making only 340rwhp. Take it to the track and see what she does man. If she disappoints you there, then there is something really wrong.

For what it's worth I never hear anything good about those TCI converters. If you locked it for a pull and picked up 40+ rwhp I wouldn't even bat an eye about it.

As soon as I can get some runs In I'll post my times. If I'm still disappointed then I'll go with a different cam.

You can't complain about the number when your on the dyno with an unlocked TCI converter. Go back to the dyno and lock the converter. I bet you'll be happy with your numbers after that.

Nice to know but that doesn't help solve the OPs problem at all.

And you won't be any better off.

If you're going to blow money on something, get a quality converter from Yank, Circle D, etc. But if you're not going to lock it, you're still going to show "low" numbers.

Unless your car is a large stalled auto that was on the same dyno the same day as the OP, the numbers do not mean anything.

Dynos are tools that are calibrated differently and things like loose stall converters drastically skew numbers.

Slowhawk is the one who spec'd and dyno'd the 348whp setup i said in my previous post and the track times backed it up 114-115 every single pass almost 116 on street tires in sub 60 degree weather. Take it to the track and rip.

Stumprrp- what was your time in the 1/4 and 1/8th? What was your 60ft? I'm getting some et street 2s this weekend and possibly going to the track. I only have 1/8th around me(Beaufort, sc) but I'm trying to go to Darlington this weekend. Hopefully It rips hard at through track.

It'll rip. It was bone stock 100k mile suspension with 255 ET streets, 3600 converter and 3.73 gears. 1/4 was always 11.90-11.97 and the 1/8 was around 7.6x. MPH was consistantly 114-115 and 90-91.

Race weight was 3460 so that helped a bit.

With the setup I posted above the day after that dyno sheet my car ran 7.8@89mph with a 1.78 60ft in 2500+ft DA. Race weight was around 3750#.
