Wow awesome info saved to read it all in a short time, thanks just got in ,but yeah I know Killercanary has got a wicked quick car when did he swap heads? Thought he had 165s, I read 185s only flowed slightly better then the 165s in flowchart comparison I think they gained up top no doubt, anyways Fordstrokers (thought about DSS) has got the same price on a 347 I dont know about 165s on a 347 it would pull down low but choke too soon, Id rather have the cubes though, 185s on a 306 would work but of course it would get it on in power a bit higher up so cammed and geared ok, and Ive enjoyed these 165s for going on 6 years now and dont think I could be sold on a Trickflow, just cause of the dyno and flow charts Ive seen, I do appreciate the replys dudes and Im looking forward to setting this car up nice, I plan on keeping it till gasoline is no more. Right now Im thinking 331 185s and if I can KB, or Vortech it later thats for another thread
BUT Iam about ready to start calling and making a decision soon as I can compare what Im getting in the short block.
I was worried 165s would be a bit squeezed up top, and if the cost of re-doing the 6 year old heads is half of going 185s Iam stepping up.
SEE, I thought you were running the smaller head. I remember reading the write up on your car in one of the Stang rags a while back so I was hoping to know for sure, and your running the FTI for the smaller cubes? Im going to look into a custom grind too, cam makes a big difference. I got an inquiry about the Tweecer in the tune section so Im trying to stay as close to budget as I can because Im trying to do the engine, the tuning device, AND buy a daily driver truck while the Stang is on stands. If I can run the 165s so much the better, but If I think long term down the road for a power adder 185s would be better. I can order the short block and wait on the heads, hurry up though! RNH IS BOOKMARKED.
I too was worried about the the heads choking me up top. The heads, my old cam that was designed for a stock stortblock, my 65mm TB that is the 94-95 setup, and my small exhaust led me to believe that this thing would peak in the 5200-5300 RPM range since the old combo peaked at 5500. We did degree the cam in a little differently, and the only changes to the old combo was the addition on a holley systemax intake, the shortblock, and I'm running an AEM standalone now and I ditched the MAF. I was shocked to see just how high this mismatched combo pulled. I made these pulls to the rev limiter and as you can see it was just starting to sign off. I didn't want to rev it much higher with the pedestal mount rockers I run. I will add that I firmly believe that larger heads would have produced higher numbers, and that is a theory that I should be testing soon. I hope to pick up 20-30rwhp with the TB and head swap with no other changes... I hope I'm not being too optimistic. I'm going to continue to work on this NA combo until I get as close to 400rwhp as I can before I put my turbo kit on. Its killing me to see it sitting here collecting dust, but I'm sure the end result will be worth it. Plus a 400rwhp NA 331 is still going to be a blast to drive in the mean time. I just hope I don't run out of injector before I hit that goal as I'm still running my 24's.
Nice, But whats with the lean spike at 2300? I think you will be stepping up to a bigger injector soon, but I'll take your 24s, I keep getting outbid for a set
