i took out the 066 in my 40 yr old 389 and put in a 2801. the engine leaks and blows but she runs darn good. has a performer intake with 600 cfm holley, stock exhaust, 2400-2800 stall, 3.36 posi. the looser converter really helped the idle. the stock convertor was just too tight. ended upputting a mini starter to be able to run the timing up to the point she likes it at. now she idles good, runs good, sounds good. yours should sound really good with headers, a little lopey with good low speed manners.

I have one in the 400 that just came out of the GTO. Engine is a YS 70 400 with 13 heads. Not a bad cam. Runs on 91 up here @6000'. Good power from 2000-4700 rpm. This is with a 4 speed and 3.55 gears. Also got 16MPG on a 500 mile trip running 65-70.

I am running the Summit 2802 in my '70 Judge, 400 .030 over, 1.5 roller tip rokers, #12 heads (72cc), 4-Speed and 3.55 rear.
Idles very nice with a hint of a lope and runs very well on pump gas. Now if I can just get that slight hesitaion out of it at cruising speeds! |
