Thanks Jay!

How much total mechanical advance (no vacuum advance) usually turns out to be optimal with TFS heads on a 462 or similar build. Thanks, Chuck

Many thanks to everyone for providing helpful and detailed information. It will be helpful in the future. Chuck (S)

Barry, Thanks for the additional information. I ordered 3/8 .141 wall from Smith Brothers this morning. On a side note, when double checking everything before ordering, I spoke with the people at BAM lifters about cup size. They said it is some special design allowing the use of 5/16 or 3/8 ball ends. I had never heard of that. Chuck (S)

I'm ready to order pushrods and I want to order 3/8". Block deck is 10.150" and square, heads are TFS un-milled, HS rockers (ball and ball oil through pushrod), BAM solid roller lifters, intake is ED RPM. The pushrod hole in the intake is .625" which leaves .125 in all directions with a 3/8" pushrod. I think the pushrods will clear the intake. However, I'd really appreciate those with a similar build to share your experience using 3/8 pushrods.

I'd also like input on wall thickness for the 3/8" pushrods as well as input on the oil hole size in the pushrod (restricted or not). My instincts are saying not to restrict but I'd like your input on the question.
Thanks, Chuck (S)

Correction: .015-.020 bolt to bolt.
