Default LS6 cam or Modern equiv in SS454 Monte

ok, i know this is a yenko page - but i also know alot of you guys run in FAST and Pure Stock....

so - i own a 70 SS454 Monte - It has the original LS5 - but previous owner put 9:1 flat tops in, and left the rest of the motor stock including the LS5 hyd cam.

The car has its TH400, and 3.31 posi - i've been tweaking it with timing and carb tuning this year and finally have it running quite good but as usual, its not enough [img]<<GRAEMLIN_URL>>/laugh.gif[/img]

so.... i was thinking, i have an original OE LS6 camshaft, and a set of closed chamber oval port heads that have been mildly ported and LS6 valves/springs installed - they had some bowl work done on the exhaust side. They would bring compression up to about 10.25:1 - (10.5 if i use a shim gasket like they did back in the 60s)

Question is - for a regularly cruised vehicle - should i go with this LS6 cam, have Cliff Ruggles mod the Qjet for the cam and run with it - or sell the OE cam, and go with something modern that will work with a 9:1 454? I'm a sucker for original equipment HP stuff... but i don't want to put too many mismatched parts on this car.

i intend to keep the stock manifolds and functional AC [img]<<GRAEMLIN_URL>>/laugh.gif[/img] i know more than a few guys who drive ACequipped L72 cars around Detroit without issue - but they are Camaro's not the big Monte!

Any help would be great.

Cheers

Aaron
