Im a new member but I've been reading these forums for a while, some smart guys on here and some Awesome Cars! My question is what size of Throttle body should i run on my New Engine??
347 .040 over, Scat crank and rods, Probe srs flat tops, 185 AFR heads, Bullet custom grind .601 lift, .226-.234 duration @50 112 seperation. 11-1 compression. Edelbrock performer RPM 2 intake. BBK 1 5/8 long tubes into 3inch Basani X-pipe. My intake opening is only 70mm but i can easily open that to suit a larger TB. I hope some of you guys can take the time to read this and give me some of your advice.

Thanks

 

I think I will go with 75mm, probably not enough motor to go bigger. It will remain N/A.
