I'm building a 67 440 to put in my pickup and curious as to what cam I should go with. The engine has been bored .020, I'm using a flat top piston with .991 comp height and 452 heads. The block and head mating surfaces have not been cut. Best I can figure is somewhere around 9.3 compression using .020 steel head gaskets. Trans is a 727 with factory convertor, not really sure what it stalls at.
It's going in a 77 D100 swb, 3.23 gears and 28 inch tall tires. The truck weighs 4100lbs with me in it. What say you.
if it is below 9.5 comp ratio- on my junk I go with Hughes steamroller or whiplash cams.
my 88-D100 with a bone stock 78 MH 440 with the Hughes 440 whiplash cam is awesome! very choppy but smooths out about1800-2000 rpm for the street truck. recurve dist.- fatten up the 650DP with a stock MH converter -any of my gears 3.91-3.23-2.76 turning a 29x15x15 M/T running the 2.76 gear at the moment for longer cruzing. sounds like a Funny Car cruz like a Chrysler New Yorker on the streets. idles along in 3rd gear 1200 rpm @ 25 mph in town choppin wood as they say.
I run 2 Hughes "steamroller" roller cams in 318s and 1 "whiplash" roller cam 318 and 1 440-whiplash flat tappet cam all in trucks on the street. they all work well with low comp stock everything as advertised. fatten up the carb and recurve the dist with a set of 925B springs has been all that was needed with them.
I have had the one SB roller cam in a few engines and over 200,000 miles on it now not one problem with them.
got about 27,000 miles of fun on my flat tappet whiplash cam now.
I am sure there are better faster cams out there but on lopo engines they work really well in traffic.
