Truly amazing what they accomplished so long ago.

Congrats! :drinks:

Send it to @HALIFAXHOPS and maybe he can make it work again.

John will be back on this evening. He will contact you.

Sitting in the waiting room for my wife's first colonoscopy. I have had three so nothing new for me. I did chuckle watching her run to the bathroom last night and this morning. Well at least she got her steps in. Lol

The 800 AVS will certainly work but may lose some HP to the 850. Both need to be tuned to be optimal. What makes you hate the 850?

This. However, A complete list of your cars current condition and what your planned upgrades will go a long way to getting the answers you want.

Tried to send you a pm but your box is full. For Sale/ Wanted - Big Block Engine - 3rd Quarter

Welcome. Something like an Edelbrock Performer intake manifold and an Edelbrock 1406 600cfm with electric choke should be trouble free and pretty much bolt on and go. Both can be found used from time to time to save money. Dual exhaust with no larger than 2.25 pipes and mufflers of your...

Larger exhaust valves than your stock heads and also a larger combustion chamber which will lower compression. 906 heads likely flow better as well. If you are running the stock 413 valve covers they may not fit. Early valve covers were 4 bolt IIRC. The rocker arms and pushrods were different...

Is there a carb builder someone can recommend for a carb with the fuel curve already set? Tested on a running engine for a/f ratio at idle,cruise,WOT? I know jetting may change but not excessively lean or rich on any part of the fuel curve should be doable? Something around 950 cfm on a 4150...

That air cleaner is a 74 (maybe later also) 440 piece. Nothing wrong with it but far from original. People do crazy things like painting the block engine color (or whatever paint they have lying around. If you can't see it in person you are leaving a lot to chance IMO.

Which side is rattling? Just a guess but you may have to raise it off the motor mount to loosen the header and move it enough to make some clearance dings.

Verify basics. Compression,Timing,full throttle on the carb opening. Rear gear ratio? With no known cam specs what rpm are you shifting at? What rpm does it stop pulling hard? Can you get any timed runs for 0-60, 1/8 mile, or quarter mile? Depending on the camshaft that motor should be...
