Thread: first 390 build

Tweet

A lot of us don't want to hazard a guess.. even an educated one.
Some really good folks on here gave you the benefit of there experience and knowledge. You seem bright enough to gather the info and filter out the chaff.

Continue to work with your engine builder and follow his recommendations, I think your to high on the compression... and I would've used a cam with less lift.
In it's place I'd go for more stroke, use a 428 crank and make a 410 CID.. keep compression round 9 to 1.

But that is just me. And you need to please yourself, not me! It sounds like your deep into this project and that is always cool! Keep at it.. and maybe share a couple pics along the way. Like I said in the beginning of your thread. It's nice to see you here!

thanks man I have learned alot just from today!, I will talk with my builder about the compression and cam, I feel pretty confident about my build, I guess he didn't mention stroking due to my low budget, and i respect and understand no one wants to make a guess how it will run,cause if I build it and totally be different, but I really appreciate your input,
