What is the block code for tpi 350 block
Hello, I'm new to the site. I have a 1990 Iroc conv 305 auto. I'm looking at buying a 5.7 tpi engine from a guy. What and where should I look on the block that would tell me it's a 5.7? Thanks

Look for the block number or 5.7l behind the rear of the drivers cylinder head on the block. You will also need to go with 22#hr injectors (southbayfuel injectors.com) use the promo code tuned for a discount. The computers memcal reprogramed. if you need assistance with that let me know
