for a camshaft? What do you guys think is a decent street cam etc.? I have my views, and they are probably quite a bit more than others as far as size and drivability, but would love to see what you guys think...

I'd say it depends on the size of the motor and the overall powerband. In something like a 350 or 355, I'd say that a mid 230/mid 240 cam would be big, but in a 383/396 or bigger it would be on the top end of medium.

This is just personal opinion though.

My car is still in rough tune but the 236/242, 614/629, 108 LSA solid roller in my 406 is quite tame around town. It idles great and I even drove the car to work yesterday.

My experience has been that generally a solid/mechanical cam will have better driveability than a similarly sized hydraulic.

I had a 305 that I had an LT-1 (the early 70's one) cam in, specs on that were 242/254 @ .050, mech. flat tappet.. It idled decent, had acceptable low end torque, and pulled to 7000 RPM. Like I said thats been my experience.

I'm looking in the next while to put in around a 24x/25x cam in the 355 once I get the EFI Victor Jr for the car... I'd still drive it on the street... assuming I can get vacuum LOL

What internals do you have in that motor Chris?

LoL... thats not the point here!! hahaha.

Stock crank, LT1 PM rods shotpeened, and TRW pistons... clevitte H series bearings etc. I am not worried about longevity for the motor like some. If it goes it goes... I will just do a 408.

I just gotta find the right guy to modify an intake and then figure out what I am doing for a MAF etc and the intkae might be on the car. if I could find a used miniram then that would go on the car but i'll be damned if i pay a ton for an intake thats worth half of what they sell it for.

My experience has been that generally a solid/mechanical cam will have better driveability than a similarly sized hydraulic. That's because the quoted lift and duration doesn't take the lash out of either the lift or duration.

I was over at Crane cams Co. the other day,in the R&D department, one of the engineers showed me an experimental rocker assembly for an LS series, .850 LIFT at the valve. YEAH! I was impressed. RON in Daytona

also of note: nascar engines are now into the 10000rpm range, push rod 2 valve set ups and on flat tappets, maybe they know somthing we dont? RON
