Info on 273 engines

[johnmucci]

Hi, I know I am in the wrong place but I need some info on 273 engines. Can anyone direct me to a website that gives the specs and differences between a 180hp and hipo motor.. Is the crankshaft different, what kind of pistons, etc
thanks, John

I have been looking through my favorites list for informative websites about the 273's but haven't located a good one yet. The block, heads, crank and rods are the same between both engines. The 10.5:1 compression comes from different pistons. Mopar also installed a slightly bigger cam in the HP engines.The HP had a open plenum cast iron 4-bbl. intake and a Carter AFB
carb. It also has a cast iron dual point distributor. They topped the engine off with a chrome unsilenced air cleaner and black wrinkle finished valve covers
with chrome breather and pcv caps borrowed from the 426 hemi and aluminum heat sinks which also were holders for plug wire looms.
