I'd go 75mm tb also but the 70 work fsto. say 75mm tb is for a few reasons. For one there is no down side of having everything in front of the intake(tb,cai,MAF) being as big as possible. You want as much airflow capabilities as possible. It doesn't effect anything in a negative way. The Holley intake is a 75mm opening(actually it's about 73.5 lol) and you don't want any choke points. If you do add a blower or whatever you'll want a 75 at a minimum anyway. So buy once! Also I highly recommend Accufab for the brand. BBK has a tendency to whistle and are t as good. FTI is a good choice for your cam. Ed does a great job. You probably will have to buy springs for the heads/cam change just FYI. My Holley cleared some canton valve covers. Not sure on FMS brand but the tall covers are for a carb setup are t they?
Yea I noticed that about the opening in the holley, so I'll go 75/75. I was just told that about bbk TBs, I will stick to accufab For sure.
I didn't think about needing a spring change in the heads, no big deal, I can do that in car
I have the ford motor sport valve covers, they are quite tall, probably taller Than they need to be. I'm hoping with a 1" spacer they will clear the stockers with some modifications.
