540s heads and cams
 

Looking to upgrade my 540s. What aluminum heads are you guys running? And what’s the biggest camshafts I can go with EMI Thunder exhaust? “Water reversion” I don’t have a problem putting headers on if the cam and header combo is a decent increase..

It has ported steel heads now and a Crane hydraulic roller cams...

Thanks!

Do a search on 540 builds for 1,000’s of threads and post.

If it were mine, Brodix bb3 xtra 327s, the hard valve seat option they offer, ported dart tunnel ram, Thunder n lightning cast aluminum headers, 250/260 Compcams mechanical roller HUC lobes w 0.620”ish lift, 110ish LSA, comp beehive springs with TI retainers, TI intake valve, stainless exhaust valves, comp stainless steel rockers, isky bushing solid lifters, 9.5-10 to 1 CR

Fun build above just consider upgrading the stainless exh valves to suggested series of ferrea or inconel. jmo

that’s the heads I was thinking of, Headers I was looking at also! Thank you for your input!

will do! Thank you!

we run a 540 with cast iron ported heads and bullet solid lifter cam it absolutely rocks and we turn it 6500 with alum heads you get dissimilar metal corrosion beware

Hard to beat 400+ cfm at 0.600” lift from a reasonably priced off the shelf head unported.

alot depends on the fuel system you plan on using, carb, efi what type of intake ?
