i just got thru putting 540 in 67 coronet
on alky @3800#
took 456 out put 410 in on 29 tall tire
i do think the motor will go 7 plus rpms
plus it do not think it needs to spin there
i figure the max hp is @620ish ?
the block is just a standard production
but does have girdle,crete but i dont think anyone should use a stock block in this combo
jmo
solid cam stx 22 with 1.6 rocker makes it like
720 lift
rpm heads ported max
i really think should found some 370 gears
put in the traps around 6300 i do not want to spin above 6800 rpms
