I was told that if I used the 1.6 rockers instead of the 1.5 it would change the lift. I'm not a motor guru so thats the specs the guy told me.
You seem to know a lot about motors so what is your feeling on the carb? Do you think I should replace the edelbrock with a different carb and if so...
Under load, about 3500 rpm it just goes flat for a second and then picks back up.

Yea, I have the CRB XE274H-10 with 1.6 rocker. Thats the specs they said it would be with those rockers.
I did have to adjust the float and took apart and cleaned it. I've never changed any jets. the main problem is hard starts after it's warm and a flat spot (hesitation) at about 3500 rpm. I forgot to mention, this was a rebuilt carb not new. Don't know if that makes a difference
I have a 66 coronet 500 , it has a 383 and 4 spd. Bottom end is stock but it has a comp cam, 256 & 260 @.050- 521 & 524 lift. The heads and valves have been totally worked and roller rockers. Has a edelbrock dual plane intake and I put an edelbrock 750 cfm carb on. The car hasn't run right with...
I just had my set of 906 heads done port, polish, decked all new valves, guides, seals, 3 angle valve job all for 800. I got the motor back together 2 weeks ago and what a huge difference in performance from before. good luck with yours
I just did what u want to. The cam I used is a comp XE274H-10, I bought the package that comes with cam, lifters,springs,seal,retainers and locks also timing chain set. I was told it was the most lift I could get without altering valve train.Duration is 274-286,Lift is 488-491
No, I had just started the car when all this happened. I actually turned it off and started it again and the same thing, so i just shut it down. I did notice on the top of the # 8 piston a half moon black mark. Don't know if that means anything? Unfortionately I'm a shade tree mech. Wish I knew...
i have a 70 383magnum. I installed a new cam, lifters and springs. Everything was fine for about 3 weeks and a couple car shows of course! Then i started it one day and the motor was running real rough., I had to keep giving it gas so it wouldn't stall. I checked the wires, plugs, fuel all fine...
there's a motor on e-bay for sale. heard alot of good things about em and was wondering if it would be worth it to build for my car. 66 coronet. The more I think about it I may just get a Hemi!
So many options, It's hard to decide. It sounds like the 440 is the best way to go.I just hope there isn't to many mods I would have to do to the car. I'm not to far from PA, thanks for the info. Nice motor and car!
I was wondering if anyone could tell me if a 426 wedge motor is worth building, compared to 400 or 440. I'm looking to build an engine for my 66 coronet and new to the mopar group.I don't know much about motors but do want a pavement pounder! Also if anyone knows someone close to maryland who...
