: Fit a gm crate motor in a 1969 velle ss rubadub Oct 13th, 05, 2:42 AM Is there any problems putting a gm crate motor 454 aluminum head or gm 572 into a 1969 chevelle ss four speed, farm boys post got me to thinking, not to detract from his post, thanks in advance. With a carb, no fuel injection Rob shaddow Oct 13th, 05, 3:25 AM There shouldn't be any problems, should drop right in if you have BB motor mounts, which I think you do. Am I right? I think if it was originally a small block ( I don't even know if they made 69 SS smallblocks, I don't think they did, I'm like 96.7% sure they didn't) so another BB should drop right in. I stay up TOO late! Wait, if it was a small block, which I dont think it was, I believe you'd have to change the motor mounts, other than that, even still I think it should drop right in..RIGHT?! WTF, work, brain!!!

That was was enough to sway my decision. NITRO Oct 13th, 05, 9:00 AM We just dropped a GMPP crate motor 454 in RAFBO's 72 Chevelle (4 spd), noooooo problemo. rubadub Oct 13th, 05, 1:35 PM Thank you men, this is another time this site has made my life a lot easier. Have a good one. Rob Farm Boy Oct 13th, 05, 8:50 PM Thanks for all of the good information. From what I have seen, the air cleaner to hood clearance is the biggest issue on fitting a 572 under a SS Hood. Since the 572 is a 'turn key' engine, I really don't want to change the intake. A shorter air cleaner with a drop base may be the only solution. Even though I obviously don't have a numbers matching ride, I am trying to make the car look original. I just don't believe a cowl hood looks right on a 66 used as a daily driver.

Headers will be close, but custom headers should not have to be bought..... i think hedman or sanderson have headers that'll fit rubadub Oct 15th, 05, 3:33 AM Thank you old, fat, bald guy Rob Hi-po SS 454 Oct 15th, 05, 9:43 AM The 502 needs an electric fuel pump, the 572 can use a mechanical pump. That is correct... rubadub Oct 16th, 05, 12:34 AM Thank you Hi-po SS 454 Rob | ||
