I just dropped off my 351 block off at the machinist to have her machined for the project I'm working on...I'm stroking her out to a 408. I'm going to use a Scat forged rotating assembly, but I don't know if I should run I-beam or H-beam connecting rods. With the flat top pistons and TrickFlow 205 11Rs w/66cc combustion chambers I figured I'd run in the range of 11-11.5:1 CR (also having a custom one-off cam ground). I don't think it would be out of the question that it would see a nitrous system (prolly a 150-200hp shot) or maybe even forced induction...but not right away. I'd really like it stay N/A. Each Scat forged kit with I-beams or H-beams aren't too far off in price, maybe $200-$300 dollar difference. I don't see the crank ever spinning more than 65/6600 RPMs. Should I say eff it, the I-beams are fine, or should I spring for the H-beams? I think with the set up I've kinda been planning, it's gonna make about 600 RWHP without the nitrous. Please advise...I don't want my motor grenading because my connecting rods sucked.
