got my pig dyno-tuned on Sat.

mods:
stock bottom end LT1
stock heads
comp305 camshaft w/ dual springs and 1.6rr's
stock clutch (not much grip anymore)
full exhaust (LT's into 3" duals)
NGK TR6 plugs gapped at .38 for nitrous, Taylor 8mm wires
stock 3.42 rear w/ a bent axle (that can't help anything........)

328rwhp/343rwtq



What do you all think? Is that about right for a cam-only LT1, granted it's not a big cam by all means, so i think it's reasonable right now.

I'm getting new valvesprings/pushrods and getting new axles put in. As well as a special Ram clutch that will be suited to hold the TNT 150 shot that is being put together right now.

I just hope i can get to the bottom of the "squiggly" lines w/ the valvesprings/rear axle fixed since we couldn't do anything w/ the tune. Opti maybe? i hope not.

A/F was a perfect 13.2-13.4 across the board too

Sounds pretty good, now throw on a CAI, E-WP, ASP Pulley and get your money's worth out of that cam.

Pretty good #'s Ben... Those squiggly lines are more ignition related than anything. How old are your plugs / plug wires? Perhaps the old tune semi-fouled out your plugs if it was rich...

Additionally, any idea on what the graph looked like w/ the smoothing set @ 5, instead of zero? Just curious if the power fell off abruptly or what.

Nice numbers

Good looking numbers man, Im putting in a CC503 on stock heads cant wait to see those numbers

Hybrid86Z

i have a K&N CAI already, not really a huge mod since everyone does them, so i left it out


but might do the ASP Pulley, and for E-WP?.....prob down the road when i do the LE 2.5 package

thanks for the replies guys!


and Shawn i think it might be the opti....just not being able to handle the hard revs of the motor?? gawd another 600 there for the delteq setup, here we come

Shawn 97 Z28 M6

naa.. i wouldn't think so. But if it's got a lot of miles on it. it certainly wouldn't hurt.

Hybrid86Z

not a whole lot of miles, maybe like 20K?? replaced it back in '03 before a road trip to Vegas :dunno:

I have a feeling the Delteq is going to be draining my bank acct here in the next couple days

i just ordered the Combination Motorsports EX-612 spring kit along w/ some new hardened pushrods....between those, an ASP Pully, 58mm TB (i want it for the spray, not so much gains on motor tho...), and fixing my bent axle, i should be solid in the 330's and maybe sneak a 340rwhp in there someplace!

I can only hope

I highly recommend that you do not use 612 springs.
