Hey guys, I'm new to the forums. I haven't done any engine work before and i thought that a 350 would be a perfect platform to learn on. I just have a few questions to ask if you all don't mind: I want to put vortec heads on with a edelbrock performer intake as starters. Other stuff will fall into place as i do further research. I want to keep within a small budget but I want 350 HP+ I will be installing it into a chevy astro. Other than price, my main concern is gas mileage. I have a fullsize G20 van with a 350 in stock condition with a TBI getting 15 MPG and was wondering if id get better gas mileage with a carb and more horsepower. I have both 700r4 and TH350 trannies too. If there is any info you can give, I would definitely appreciate it. Thanks!

Joey
