How many of you small block guys that are running a smaller cubic inch under 400 ci with 260+ cfm heads
running one of the hughes grinds and turning 7,000+ rpm? They are having a cam sale going on and I am interested in buying one. I understand about the lift of the cam and having heads to back it up but I'm not sure so much of duration @ .050. Does anyone run a lot of duration like 272-276 @ .050 on a smaller engine with a good set of heads? I have a 344 inch motor with W2's that I would say flow close to 290 cfm. Thwy have a 2.08" intake valve that's a 3/8 stem. They also have a nice 3 angle race valve job and ported. I have a heavily modified M1water heated intake to go on top of the heads. I have some old school 7° titanium retainers to use and I'll have to get the right matching springs, keepers, and possibly retainers if mine wouldn't work for some reason. Bottom end is nothing fancy besides a 8 bolt Mopar performance forged crank that has been knife edged. I need to get a set of H beam rods and lite pistons yet. I plan on building some 1 7/8" headers along with my own oil pan most likely. I have a old style 850 holley that I bought a e85 conversion kit for. We have never had a decent carburetor yet so if we can get this one tuned in it should be a good gain. I am back halfing the car I have now which is a 1963 plymouth valiant. I am
expecting it to weigh between 2700-2750 with driver. I need to buy a T/A or some kind of decent 8" converter. I want to run in the mid 10 range in the 1/4 for sure. I think I'll need to turn 7,500 or so rpms to do it with this small engine. I am open to any ideas or opinions on my build and camshaft slection. Thanks FABO
