spend about $8000 and do tons of research if you want to do it n/a, or, put a nitrous kit on it and spray till she blows.

those numbers were achieved with a 750 cfm double pumper, open headers and no accessories on the front of the motor. and it's not a 305...
what is the goal here? easy, fast combination or wanting to learn how things work and what makes things go fast?

Ive looked into them....pretty sweet deal really w/ a 2 yr warranty and the TPI can go on it without voiding the warranty.....I thought of a blueprint 355 w/spray in a Triumph TR6......
well i want to go fast without spending alot of money. or how about JEGS High Performance - Blueprint Engines SB-Chevy Short Block Assemblies with may be Edelbrock Small Block Chevy Victor Jr. Cylinder Heads with a comp cam setup?

Spending $3000 on a 305 engine is a waste.

Dude, I have a 305, it pulls like no other I spent about $3000 to turbo it w/ many supporting mods. I'll get some dyno number soon...but I bet Im close to 325rwhp...with a 305.
