I'm getting close to ready to start on my 70 swinger & currently in the process of building a 471 stroker with a 73 #630block
Molnar 3.915 crank, 6.70 rods & srp 1.320 pistons. Trickflow 240s up top & a howards solid flat tappet 260-264 @.050 .616-.620 lift, I was told this would be a great choice by a howards rep for a street/strip. I recently talked with Hughes engines since they have the identical cam & asked him what he thought, he punched in some numbers for me & said this cam is too big for my 11.4:1 scr & would be a pump gas engine at 12.5:1 so now I'm kinda stuck a bit, with 0.27 cometic gaskets .000 deck & milling my new tf240s down to 75 cc I can get 12.13 scr. I was wondering & hoping if I'm thinking correctly could I get a 9 was timing set & advance my cam 6-8 degrees.
I believe I have a 8.6 dcr with 185 cranking pressure. Hughes says 195-200 is safe & advancing my cam 8 degrees puts it at 199 psi. I trust Hughes but howards has this at needing 10.5 minimum. Any advice would be great. Thank you
