a little build-up confusion

[Anonymous]

Hi all.
It's summer again, which means a summer job BUT money to spend on the old 'stang
Anyway, I have a few questions that i hoped that you all could clear up for me.
1) I have custom forged Ross Racing pistons ($600!!!), polished rods, ARP rod bolts and Total Seal custom moly rings that i filed for 150 shot of NOS to blead off excess pressure. Could the motor handle a 150-175 shot of the gas USING a direct port injection system? I know that a plate system would blow the motor to hell but i was hoping that with a copper head gasket, secondary electric fuel pump, and direct port nozzles it could handle this amount
2) Is $1300 a fair budget for a T-5 conversion and 3.73 rear gears? I DO NOT have a clutch so this will have to include hanging a clutch pedal, etc. but i don't think that would be too hard or expensive
3) What would be a REALLY HOT cam recommendation? If i go with the T-5 and 3.73 rears i'm definitely going HOT. I'm 17 and power is more important than driveability. Hell it's an old car anyway and so dependability is really relative. OH YEA...how do you or can you change the cam without pulling the motor??
thanks and I really appreciate your help so far, 1 year ago i had barely changed the oil in a car and now i've completely re-built the motor with
NO help at all (didn't even use a mechanic! well, you guys count

1. Yep the engine will take a 150 shot, esp with the forged pistons. Make sure you balance the rotating assembly and replace the rod bolts with ARP or some other equally good bolts. 5/16" Small block Ford bolts are a direct fit.

2. That should be more than enough to do the transmission, if you do all the work yourself. If you pay someone else, expect to pay for 10-12 hours of labor.

However, the 3.73 gears might be a problem. What rear end do you have? If it's the stock 7.25", finding gears will be a problem. That means a rear end conversion needs to be done as well. Between the tranny and rear end, $1300 might be a stretch.

3. Hot cam......what kind of head and carb will you run? You can get really hot 300+ degree cams ground, but unless you have the airflow to support it, the engine will be a pig. You need to look at springs, valves, a 500 cfm 2bbl, headers, duals........gotta get the airflow numbers up there.

An internal combustion engine is nothing but a big airpump. You have to open this one up so that it can move some air.
