    Will I have to balence the rotating assembly on forged rods and pistons?

    I’m planning on putting high comp forged rods and pistons but keeping bore and stroke stock. I had someone tell me I will have to get my rotating assembly balanced. Is this true? I thought it was only if you change the stroke and bore to a 377 or 383? Thanks, Korbin.

    Good cam specs for build?

    So I had plans to do a 377 stroker but my 450r bike blew up bottom and top end and the suspension has been out for a while so I’m a bit tight on play money. Rather than doing an all out 377 build iv decided just to do a mild build on a 350. What are good can specs/can you recommend for the...

    Top end vs 383 stroker

    So, im aiming for about 430 crank HP. Is it possible to hit this without messing with bottom end. What would AFR top end kit, pistons (aiming for 10:1 compression ratio), a cam, Holley 650 cfm, and long tube headers get me? Or is it worth the extra 1300$ to 383 stroke it. Seems like I can get...

    Best engine swap for 1990 gmc 5 speed manual

    I have a 1990 gmc k1500 regular cab step side which I am redoing. I picked the truck up for 3k no dents or rust. In my area I can’t find a running one without dents or rust for under 5k so I’d say it’s a good deal. I’m doing a project in it. Want to do a classic 90s truck. I’m getting it...
