going to the track what should i expect?
sorry didnt know where else to post this but here goes..
had my car for 2yrs and so far ive modded damn near everything.
Im going to the track on friday for the first time for a club shootout texasfbody vs sanantoniofbody and im wondering about what im gonna run. I know its not gonna be the quickest girl out there because of the gears but i wanted to know about what to expect.
the mods
rebuilt 4bolt roller 350 block from a 97 vortec truck
10.5:1 compression
comp cam .503in/.510ex 224/230 112lsa
ls1 beehive springs
p&p 305 vortec heads
edelbrock rpm airgap intake
procomp hei dizzy with 50k coil
edelbrock performer carb running rich for the track
edelbrock proflow aircleaner
cowl hood
hedman longtubes
2.5" true dual exhaust with h pipe dumped before the axle
fuddle 10" 3500 stall converter
greaseymec fully built 700r4
still have the stock 2.73 open diff
so what do yall think this combo should run?
Its all bracket racing so the auto trans and 2.73s should run consistent but id like to know what to expect for my et.

The 305 Vortec heads are really restricting it unless they are ported.

Re: going to the track what should i expect?
yeah he said he ported them---"p&p 305 vortec heads", that combo sounds good, but the next thing i would change is those gears, put some 3.73's and a posi and you will be good to go. as it is right now i am not really good at guessing at times. just watch out, you will be spinning off the line

Re: going to the track what should i expect?
yeah even with the port and polish those heads are the bottle neck... GM put them on the 305 for a reason... not to mention that any home porting of them probably hurt the flow... probably still around 199 cfm @ .500
a set of 062s intouched would beat that
i am gonna guess low 13s
