Newbie Drivetrain Ques
Hello excuse my ignorance I just got a 2004 Mach 1 and know very little about it.
Is it true it is an aluminum WAP block? If so how much hp can it reliably handle? The manual trans engine have a forged crank, it isn't as stout as the SC Cobra crank is it? With its high compression ratio how much boost can it take? At which point are the rods and pistons weak? These are returnless fuel systems correct? At which power levels do they become restriction? I see some swap cams but that seems expensive are they worth the expense? My goals is a power adder and 450 rwhp. I don't know about Eaton swap or SC or if I can save my pennies a turbo kit. Thanks |

Many factors in such an answer, power is just one item, RPM it ran to, etc. I've seen 750 all day long. But, I personally found a Teksid block for their reputation to handle large amount of power. I am only talking the block here. Quote:
(miss read your question... ) Not sure of the PSI limit but HP level ~450hp is safe for a stock motor that has been taken care of. I have seen people make 500 for a long time but that is getting close to the edge. Don't be afraid of the high compression aspect of it, the real issue are the rods and piston material, not the compression level. Think of it like this, low compression motors require more boost to make the same power that a high compression motor will make on boost. The trick is in the tune. I made ~750 @13ish PSI with 11:1, I think I was at 650 when I ran the 9:1s. Everything else in the motor was the same. 450-500, Yes, this is the week spot of the motor, if you do a built motor go ahead and put a billet oil pump gear in there too. Quote:

Re: Newbie Drivetrain Ques
Hey thanks for all the info!
It's good to hear I can get 450 without touching the long block. I read they used a cast crank in the auto trans don't really understand the logic behind that (I prefer auto) but I am glad you say mines is pretty stout stock. If I think I will be happy with 450rwhp?!?!?!? LOL I hope I will. I know people say once you achieve once hp goal you will want more but I am limiting myself to 450rwhp to save myself from jail cells or cemetery. I briefly had a 95 GT with TFS top flow kit (300 rwhp) and I acted a fool with it whenever I had spare time so I don't want to cause myself an early demise Quote:
