Hi

Got A 70 Mach1. 351c With Holley 4bbl,edelbrock Mani, 3 Spd Standard Shift.
My Mech Checked It Out And Said I Have A Racing Cam........
Question To Everybody--- What Is It And What Does It Do. Also How Many Horse Power Would I Have With It?
How Many Horspower Without It?
I Plan To Keep This Car A Long Time And Want To Pass It On Someday In Great Condition.
For The Long Run Should I Take The Racin Am Off??????? And How Hard Is That To Do??????

Every engine will have a camshaft in it. The camshaft makes the valves open and close, letting air and gas in, and letting the exhaust out.

There a different grades of camshafts. A stock cam will open and close the valves at different times, while the engine is running, than a race camshaft. So if you took the racing camshaft out, you'd have to put a different camshaft back to replace it.

A racing cam can make the engine more difficult to drive as it will make the idle rougher and the engine will not run as well at lower rpms.

It is difficult to change cams as the engine will have to be partially disassembled and then carefully reassembled with the new cam.

It is not possible to accurately predict your horsepower with out knowing more details about your engine.

Have you driven the Mustang yet? If so what did it drive like?

Basically a "race" or performance camshaft will open your valves further(lift) and hold them open for a longer period of time(duration) than the original camshaft will....This only works well when it is used with the proper package of other parts..Installing a race cam in a near stock engine usually hurts performance more than it helps...Of course it also depends on what your mechanic thinks a "race" camshaft is?..What some people consider a race cam others might use in their daily driver..

You are falling for an old wives tale.

The 1970 Mustangs equipped with the C engine were a bit hotter than their counterparts. Thus the old time mechanics said they had a hotter camshaft inside. Nothing to do with the other odd improvements to the engine from cylinder heads on down.

This might be true but with the addition of a edelbrock manifold and holley carb it is not unreasonable to think that someone may have added an aftermarket camshaft as well...

Nobody here has any idea what cam is in there. It could be anything.

take a video of the car idling, we can then give you a better idea of how big the cam is.

Impossible to know w/o Cam Specs. Can't always tell by listening. Solid roller cams r race cams, unless u buy the Xtreme Energy Solid Roller street rollers by Comp. U can still use steel Dist gear with these cams as they don't have huge spring pressures,and very gentle ramp rates, that's why they're designed for street/strip.
