First time track results

Thanks for the input guys. I kinda had a feeling my heads were holding me back a little, These heads were ported alot by my engine builder. But there proberly is more to heads than just porting and polishing. For exhaust I was thinking of running 3" to 2.5" x to my flowmaster 40's 2.5" to flowmaster tails 2.5". I already have the mufflers on my car. Thanks again, any other suggestions?

Your exhaust idea sounds fine. As far as head porting goes, more is not always better. You can do more harm than good with a poor port job. It would be interesting to see some flow bench numbers for your heads, but as you said, you don't have any.

I've always been into proven parts. That's why I am willing to drop the money needed to pick up a good set of CNC ported, flow bench tested heads. You know what your getting, and what they will be capable of. They do cost $$$, but are the best money you can spend on your engine IMO. If you are on a budget, you might be able to pick up a nice used set of heads for a good price. I've always been an AFR fan, but others may have their own opinion of what's best. Let us know how the project goes.

Well I made it back to the track on Friday. I have an all new best. I ran 12.64 at 107 with an 1.86 60ft. I ran in street trim with 285/40-17 nittos. The only changes I made were 3000 stall from neal chance that foot brakes at 2800 and flashes to 3500 and 1-3/4 headers with 3" x-pipe exhaust. I still need drag radials. I did change my springs and brakes earlier this year but I don't think they made a difference.

Well I took my car to the 1/4 for the last time this year. I ran my best time so far. I went 12.43 at 109 with a 1.86 60ft time. I think my 1/8 was 7.9x. (time slip is at home I'm ashamed I don't remember.) I did mix some 110 race gas and bumped my timing up to 38 degrees, because my compression is close to 11:1, (what a difference that makes even on the street I can feel it)This was done with my street tires. I guess the plan is to get a set of 15 drag rims and et streets. I'm going to replace the valve springs and put some 1.65 rockers next and see where that gets me. I'm hoping I can dip into the 11's but I'm not going to change the suspension to do it because the car handles awesome. I want to just go as fast as I can in street trim with some drag tires. What you guys think I can do it? Here's a pic

Nice times...I think if you swapped you 1 5/8" longtubes back on you 60 foot times would pick up. Quite a bit more torque in the mid range. Keep at it and the 60 foots will fall. Mine does not like to hook as well either. In fact it only dead hooked once...man that feels sweet!
