i think any thing over 500 cid and you will want better heads you did not tell me the casting numers on your heads .the gm O ports heads are good for smaller builds BUT the ex port is not to hot. a set of 990 gm rect ports would work better there are may heads out there but the time you do your heads it would be better with a set the flow more . my old 572 i had to make headers for it and you would with you truck i think 2.1/4 to 2.3/8 tube is what you want , the prices on this stuff sounds in line

Ya you are right about the heads .A guy I know said he has a set of rectangle ports for 800 dollars that will bolt on nicely to the big M block.How many cubic inches you running in the olds?I am starting to think I need to bring my sights down some,hell I still want to drive it down the street on a nice day.

in my50 chevy 548 blown in my gto 630+i have no olds?and i do drive them on nice days eveyone knows when i am coming ii have had some wild big block on the street if i have to say so my self and they all were driven on the street

How much horse power do you think I can make with the 540,and some GM casting rect. port?No nitrous

had a 548 14.8 to1 lunati cam 748 748 on 108 lsa i think it was a round 279 at .050 1150 9377 holley on a re work team g intake with 990 heads that i re work put 2.250 intakes valves. 2.1/4 headers to 4inch ex with a x cross i drived this on the street in my gto IT ran very good .that engine had to make 750to800 hp easy
