I have a 350 TPI and I'm doing a complete rebuild. I already got the engine torn down and the cylinder walls look good and the heads need a little work. What would you all suggest for a 350 TPI rebuild kit. I am wanting low-end torque and HP. I'm looking to get maybe 280-290 HP? My budget for the kit is around $450 and I have seen a few kits on eBay for around $300. If you have any suggestions please tell me. Thanks!Engine: 350 TPI, 1987 IROC, MAFThanks for your time!
