Pete,

What were the results that you liked about this set of timing numbers? Would these be for ported top end, ported heads etc or doe it not make a diff?

[Pete]

The same reason smaller exhaust cams make more power in the LT5.
Start to open exhaust a little later less loss

I know there is long techy term on the web i'll leave that up to somebody else to look up copy and paste.

We tried 108 In with what i remember to be 115 or 116Ex gotta look it up,it was on advise from one of the big cam companies.
Not good at all,loss through out basicly it was the worst.
Some should stick to single cam motors.

Exhaust opening way too early, intake closes too fast.

Can somebody post Marc H's Cam Timing event pictures on page 10.

[QUOTE=Dynomite;87525]I am now using Intake 114 and Exhaust 108 for ported top end (plenum/injector housing/heads)and SW headers with SW 3 inch exhaust (no CATS) 91'.

Marc suggests to have a broad torque and power range (3000 to 7000 rpm) use I 114 and E 110. 114/114 is nice when trying to tame idle roughness out of a cammed engine. I

I notice the factory cam timing specs may be different on a 90-92 versus a 93? I see on one diagram that the 90-92 are set at I114 and E114. I assumed that is factory engine with the pinned settings.

The single flats on a 91' camshaft/vernier plate have a play of up to 6 degrees (crankshaft degrees). I think 93's have double flats with the play cut in half or 3 degrees (crankshaft degrees).

Stupid question: How does Stage One cam grind effect cam timing on a 91 engine with the same mods?
