does anyone know if the vortec truck oil pan will fit in an fbody? or is it better to use the fbody pan ? i thought there was a windage tray in the fbody pan not sure of the turck pan, guess ill have to pull both and take a look

nevermind figured that out...

new question: i am contemplating a T5 swap, i want a T56 but due to the expense a T5 is all i can do for now, and i figure i get a T5 run it till it doesnt run and swap in a t56 half the work will be done and maybe by the time the T5 dies the T56s will come down in price lol anyway besides the fact that it will be less consistent(becuase of me), what are your opinions 700R4 vs T5?

ok t5 swap is scratched as i have a new problem i removed the heads to inspect the shortblock because my lifters looked a little muddy when i swapped the LT1 cam in yesterday, when removing the heads i hit the valve cover lip with the mallet and took a chunk out so now im forced to take the heads to the machine shop, luckily im selling some of my parts for 700$ and it will cover the head work pretty easy, now ill be using a ZZ4 cam and better springs so all you guys should be happy, the shortblock looks great however i now believe the po's story about the engine being rebuilt a short time ago with marine performance stuff. im gonna install the new HV oil pump and and reinstall the oil pan and wait on the heads.... so how much power should i make with

4 bolt vortec block,
vortec heads rebuilt with manly race flow valves(1.95/1.5) 30 degree back cut etc
zz4 cam
performer RPM intake
Hooker 2055Rs(1 5/8" primary 3" collectors)
into a SLP LM for 4th gens(single 3" glasspack dual 2.5 outs)
stock Qjet and HEI

sound like i should be solid in the 13s? i have 3.23 gears now but i will try to get some 373s in before the end of the year and the stall should be around 2500 the rear tires will be a limiting factor im sure 245/55/16s as well as the stock suspension, the car is pretty much gutted right now so should be pretty light for a thirdgen no egr no ac no AIR no interior im even thinking of getting rid of the stereo and speakers because im sure its gonna have to be way up to hear it anyway, itll have a fiberglass hood and a aluminum driveshaft im guessing somewhere around 31-3200 it was 3350 from the factory according to the build sheet any guesses?

:shrug: Didn't take me much to go mid 13's.

Now I have a crap load into my 355 but I run 12.0@114 :D

thanks kat thats very encouraging i was hoping for numbers close to the zz4

I have a set of cast aluminum valve covers for center-bolt heads if you're interested, been on the shelf since 2004. Very strong sealing and very easy to torque. Fitted with same oil fill and PCV locations as factory TPI setup. Cheap. I work in East Stroudsburg so shipping might not be necessary.

T5 shifter hole won't be in the right place for a future T56 swap unless you hog out a hole big enough for both locations. Clutch master cylinder holes should be compatible.

If cost is the big factor I'd go with a TH700R4 and an S-10 converter, add a Vette servo to firm up the shifts a bit.

thanks crane i actually got a set of valve covers with the long block, and i have a transgo kit, corvette style servo and a 2500 stall converter now, gonna keep the 700r4 becausee its cheaper to get the car running this year
