Tune up help!

My friend bought an 81 tubbed camaro with a 454ci, 750cfm dbl pumper, 3spd auto with ratchet shifter, 4.55 differential. That is all he knows about the car and he is trying to tune it (1/4 mile time was 14.24 sec shifting @6000 rpm at elevation of 4000 feet). My stock C5 vette with 350ci and 2.73 gears runs the same! Can someone please help with a little tune up info...we are mechanically challanged...lol (i.e. timing, jet size and anything else that would help make this thing go faster)

damn...... thats freakin slow... how many passes did he take?..... either its runnin like shit... or its not getting enough gas.. if you can get any more info that would help

it runs on racing gas 125 octane, we made 5 passes, new 3" driveshaft, spooled rearend and new axles, no exhaust just straight headers.

is it running hot or anything?? i would have to get an idea what size cam it is for an idea on the timing, and what kinda ignition your running, wires plugs and etc... oo and with those gears is he topping out b4 the finish

dont think it is running hot but we will check, he does not know what kind of cam, lifters, pistons he has. Timing right now is advanced 28 degrees, tomorrow we will check plugs, compression, ignition. Thanks!!

is it a built 454 or a stocker from a truck or something that was thrown in just to help sell the car?

The car was built in W.V. bought at auction and brought to Montana so we do not know much about it...of note it came with a distributor that was a magneto (weird) the was recently changed to a standard distributor and the carb was a 850cfm dbl pumper and now changed to a 750 we were also told it was built for nitrous but none was installed.

does it sound like a hot car?? does it rumble or sound like a fast car?

and is the motor shiney.... lol

The car sounds awesome, nice (cam) lope when idling

sounds like a slipping converter, if its running smooth, sounds good, but its an auto, could be shitty converter, or a worn out one. causing massive slippage and slow times.

yea that is very possible

Thanks for all the help, we wound up doing compression checks and zero lbs on cyclinder 8...we tore the heads off and thought we would be lucky, found a bent exhaust valve there but what makes it worse the #6 cylinder wall was scored badly (deeper then 30 thousandths) and a small part of the piston was actually melted!!! So time for a big block crate motor and $7000.00 plus :-(
Oh well thats racing. Again thanks for the info.

it was running great with a dead cylender??????????? didnt see that one coming

lol i know
