They have some beautiful on the shelf items for Mopars. Vic is a Mopar man himself. He is at PRI this week so call him next week and see what they have to offer. These are going in my build for next year. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

Skip the Chevy pistons, not only is the valve angle wrong but the valves in a Chevy aren't on center with the cylinder like the SBM. I've had Wiseco, Diamond, and Ross pistons in the past and all are high quality and you can get exactly what you want for just a little more money over a shelf stock. Well worth it in my opinion.

Talk to Vic next week and you won't be disappointed. Tell him John Cadamore recommended him. If you need comp height or weight let me know. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

I think that would put way too much stress on this block I have. it does have the .927 pin and weights 438g. that was off their site. the other pistons for sb mopar are flat top and dish. 12:1 would be the best I can do with a flat top. my indys have a 60cc chamber. http://www.youtube.com/watch?v=aIxaesJ190U http://youtu.be/lCZAaN7fFLg

Are you calculating your compression at deck height and with that compression are your going with cometic gaskets? They will make you what you need. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

I have chevy blanks in mine that the valve pockets are mopar and I had some dish put in to lower the compression a little... they will treat you well and they have been quick.... the last set I got took 3 days for my Rampage...but I also know the owner

Did you have the block sonic tested? I have seen big discrepancies in wall thickness, etc. with 360 blocks over the years. 7956759-eddy2.jpg (315 downloads) Fastest 300
