Heads or intake Okay so I'm doing a stock bottom end rebuild with a Hawks sinister cam specs on cam are 230/236/591/601 I'm looking for best bang for my buck iv currently got stock 241s and I'm wondering if in better off with a set of 243s and the doorman intake or just pass on better heads and go fast 92mm intake I'm trying to build a street car/ play toy I'm looking for a power band of around 1800 _6500 all ideas on how to achieve this goal reliably are aprecapeciated shooting for 450 or so at crank
I would lean towards purchasing the best heads your budget will allow. Sure, buying heads/cam together is more convenient..i.e., one tune, easier to install at the same time. You have a good amount of options. You could go with stock 243's which might add 15-20 hp and add a used fast 92 or 102. You could also have your 243's ported/polished. Advanced Induction and TEA offer fantastic porting programs. One other option that I think gets looked over is...keeping your 241's and have them worked over by Advanced Induction. They offer a 219cc High Compression CNC program that really makes good power while utilizing your exsisting zero cost heads. Lastly, if money permits and you want to go aftermarket..Trickflow/BTR, Mast, and AFR, Mamo Sportsman are awesome but pricey. Im not a salesman lol, and since we all have opinions...My current heads are AI 226cc 243's and I'm super happy with them. I think it's one of the best option outside of aftermarket. Sorry for the long post, I just think it helps to know your options and make decisions for the big picture. Good luck.
I missed it before, but you mention wanting about 450 hp at the crank. That's like 380-400 at the wheel. With that said you really don't need to do anything since you're probably already there lol
I missed it too. Ok so scratch my novel I wrote lol. Yeah with that cam, headers/exhaust he should be close 400 at the rear already. Which begs the question, since your already there...why stop there?
If you have the money to buy a good intake like a FAST, forget it and then spend a few hundred more and send your 241's to AI. They have an excellent CnC program that will make the 241's flow almost as well as a set of ported 243's and will make plenty of power.
