Well about a month ago my little 150k mile mouse spun 2 rod bearings and one main bearing. It ran strong until then had a victor jr, holley 650, headers, 488/510 cam roller rockers gear drive, 125 power shot, 4:10's factory posi, it ran damn good on the spray but the oil pickup broke and fell into the pan i couldnt shut her down fast enough oh well.
About a week ago i picked up a 454 with 1000 miles on it for cheap i mean dirt cheap. i have been working on that ever since, i have installed a rpm air gap, comp cams extreme cam, double roller, headers, few other odds and ends still waiting on my oil pan, and roller rockers, and my motor mounts, this should run fairly good with my 2500 stall but i am hestitant on teh carb i want to run a 750 dominator but am unsure can some one shed some light on this for me or just give me some more ideas i will be have a 125 shot on this motor as well. I haev converted it to hei with a msd 6al. Let me know will have pics soon but this motor looks like it will haev to be shoehorned in the compartment with the heater box still in. its my big orange ***** hehe

A 750 carb is a decent size for a 454. You could almost run bigger. Then again, rejetting isn't really all that tough for someone that can install a cam properly.

This is a 454 with a similiar cam, intake and rollers.

It ran very well with a stock tuned Edelbrock 780cfm carb right out of the box from Summit. With 4.10's, it would pull a house and hit 120 very quickly!!!

Sounds good. Just in time for that big gas hike. I love the big blocks but my little 350 is bad enough on gas right now. But I drive it anyway because I just love driving it and getting the thums up. As I am sure you do to. Sorry to hear about your small block.

Why not bag the carb and go for injection?

Rats like injection, especially if they are bottle fed.
