most of you guys on here think I'm kind of a jerk off, but I've got a real question this time. I've got a built 4r70w with an aftermarket valve body a trans brake and a 3000 stall converter with a 4.10:1 posi rear end with a 255/45/16 drag radial. some of you know that I recently blew another n/a motor out. I've got a s/c motor that I'm going to re-ring and re-bearing. but I might actually go with forged rods and pistons also. I havent torn the s/c engine down yet, so I don't know if I need to bore out the cylinders. but this is just a general question. IF, and this is kind of a big if. If I replace the rods and pistons with forged ones from ssm, what compression ratio should I use? I'm using an m90 type blower like most people. I can't afford a turbo setup or an autorotor. personally I'd like to step it up to 9.4:1 compression with my mpx, but I'm also considering going low compression with more boost from the m90. today I got most of the junk out of the way to pull the s/c motor from my 93 tbird. tomorrow I'll get the motor on a stand and start the dis-assembly. anyways, enough rambling. What do most of you guys run on your motors, as far as compression ratio?
