How long would my stock long block stay together with about 7 psi spinning to it through a Paxton blower? If I drove it like I had some sense not banging on it, and it has around 75k on it. Thanks.
75 kms or 75 miles? If it's miles I wouldn't do it. It's not just the motor is your trans up to the job? Is it auto or a t5?mustang90ace said:How long would my stock long block stay together with about 7 psi spinning to it through a Paxton blower?

It's the block that doesn't like anything pass 500fwhp but with 75,000 miles on it you could throw a rod or a crack bearing quick if ye drove it hard but iv seen guys running 125 shots with 255,000 kms an it last two years then she throw a rod through the block but it's kinda hit or miss at that many miles I would put a forged 306 rotating assembly before you start playing with boost. The 302s between 85 to 92 an a half had forged internals late 92 to 95 were not. So the forged ones take a bit more but not muchDion11197 said:With 75k on it, it all comes down to how abused it is. There's just too many variables to say, but tuning is everything. 7 psi is a lot for the stock block, but tuned properly and not beating on it too much it would hopefully last until you can build a bottom end, but I'd have one ready.

I've seen some guys that had a blower pushing the suggested hp limits for the stock internals and it last a couple years, then again I've seen guys on 4psi grenade their internals in a week. Most of its the tune and the abuse it's given.
