I've got an 87 with a 305 tbi engine in it. It has about 130,000 on its and runs good, but I was thinking about putting something else in the future. I"m not exactly sure what I want to do or how much it'll cost me, but I was thinking about a 383 stroker or maybe just a 350. I would like to keep it tbi. What does it generally cost for the machine work for the crank and block for the stroker? How about vortec L31 heads? I hear these make pretty good power for a fair price. I know the vortec tbi intake is very pricey. Then I guess I'll have the upgrade the tbi unit to handle more power. I've seen the rebuilt units with larger bores. How would a tbi unit off a 454 work? What about a cam?- a little lope with good low end would be nice. What kind of grind would I need? I reckon I'll need a Custom chip for all of this and new headers or manifolds that'll work. I'm not looking to build a race engine or anything. I was thinkin of a streetable 300-350hp with good low-mid range torque, which I guess should befairly easliy obtained with the right combinations. What do you guys think? Opinions and comments are appreciated.
