First, I want to thank everybody that has been responding to my questions lately. This forum is great and I appreciate everybody's willingness to help other people.

I bought a set of Trick Flow 23 degree twisted wedge heads at least 5 years ago for my '81 build. They seemed like a good choice at the time. They are still new sitting in the boxes as I've never finished the engine. Well, I'm at the point where I'm ready to start thinking about the engine again and have been looking for previously proven engine combos for a 355 with these heads but am not having much luck.

I'd like to find an engine combo that's putting out about 400HP and as much torque as possible. I can find descent engine combos for other heads but am not finding much centered around the TF heads. Cam selection is proving to be a mystery to me thus far. I had also purchased some other parts back when I bought the heads but am feeling pretty confident that I need to change the intake and cam to something else. I didn't really have anything solid to go on when I bought the standard performer intake, holley 600 carb, and a Crane Powermax H-266-2 cam (summit crn-113931). I've also got TRW forged flat top pistons and then engine machine work has already been done at .030 over.

I'm just having a hard time coming up with a good combo that's going to put me in the HP and torque range I want to be in using the original block and these heads. I figured that if I followed someone else's build that was similar I could come up with similar numbers instead of trying to reinvent the wheel.

Anyway, just looking for some more ideas from you guys that have already been down this road.

thanks

 

www.ryanscarpage.50megs.com/combos1.html Over a hundred dyno'ed combinations on here. If your heads are not here figure out the flow #s and match them to something posted on this site. It will help you pick a good combination. http://purplesagetradingpost.com/sum...fo/heads1.html

 

I ran TF 23 degree Gen 1 heads on a 355 with a Crane 272, Performer 2101 and Hedman headers. After I changed the valve guides, I was very happy with the results. I don't remember the dyno numbers but I think both TRQ and HP were around 350 with a marginal Holley ProJection system. With better fuel management, I think it would have done better.

 

Check out the info in my signature; that same combo with TF 23* heads made 13 RWHP less....still good enough for high 11's in the 1/4.

 

Summit sells a bunch of trickflow combos.

I know you already have a set of cylinder heads, but this should give you something to go off of as far as cam and other part selection.

A while back I read a post on this forum from a guy who had his engine dynod after installing a Trickflow kit. His results were spot on with the numbers that Trickflow claimed he should get.

I bought the 465 HP, 450 TQ kit and rebuilt my engine to a 383. I haven't gotten to the point in my project where I can start the car so I can't tell you how it runs. I like the torque curve of this kit better than the 500 hp, 450 tq kit. You can't go wrong with having about 400 ft pounds of torque at 2,000 rpms.
