A new pony...kind of

[yellowshaker]

Guys, i had an 03 Zinc Yellow Mach 1 that i purchased new. Last month the car was totalled by a lowlife who stole the keys. I hopped in the car to stop him and ended up nearly dying when he purposely crased the car into a row of parked cars. I have since purchased a 1991 notchback that is in great condition. I have some documentation with the car for the parts that are in it, but I am a little confused about a few things. I'll start with what the guy told me it has. Stock original block, trick flow high port heads, trick flow stage 2 cam, BBK SSi upper and lower w/throttle body, MSD 6AL 2 box and distributor. Pro M Mass air calibrated for the 42# injectors. Holley fuel pump, Holley adj. regulator, and 373 gears. Everything seems to be in order but the bill I found for the cam says it's an E cam, not a trick flow. I know the guy intended to install a blower but decided to sell instead. Anyway, I found the car has an intake leak when I went to see it. I am fixing that tonight and the fuel pressure gauge is at 30 psi. I am thinking about changing to 24# injectors or maybe 30's because I plan to keep the car Naturally aspirated. What do you guys think?

Sounds like a fairly healthy setup, but actually having the stage 2 cam would be nice. I'm sure it's possible it has the stage 2 cam. How's the idle quality? It should have a pretty nasty lope on a 302. If you have any plans on getting it tuned, you could keep the 42's and save the money on buying new ones, since they could tune around injectors that big (or you could, if you go the self-tuning route). My only suggestion would be to reset the fuel pressure to the stock 39lb. (with the vacuum line disconnected), so it can be tuned easier.

The fuel regulator is a Holley and does not use vacuum. I adjusted it already and it pulls better. I am going to pick up and Edelbrock Performer RPM2 tomorrow for it and put a stock fuel rail back in. I plan to sell this BBK w the throttle body and high flow rails.

If you can check the lift at the exhaust valve it should be .568 with the Stage 2. The E cam is .498. It's a sizeable difference so even if you make a small error you should still be able to tell pretty easily.

24s should work fine for your combo.

I have a guy that wants to trade my 42's for 24's so i may run with it. And the car does have a nasty lope to it. It hits pretty hard actually. I may try to measure the lift ont the exhaust valve and see what I come up with. I'm hoping to pick up an Edlebrock performer pm 2 and throw that on this weekend with the stock rails.

Well, with the fast ramps of roller cams it doesn't take a whole lot of cam to make a whole lot of lope. If you advance them it sometimes make them lope even more. I have just a B cam in mine and it lopes pretty good. View attachment 288110

Did the previous owner get a computer tune done or just change the MAF meter?

nice combo there maryland!!!!

 

[Maryland Stang]

nice combo there maryland!!!!

Thanks Your's should sound something like that doesn't it?

 

[old_blue]

he may have bought an e cam sometime ago and just left the receipt in the car. is there anyway to call and ask him?? If he is a decent mustang guy he should be able to tell you why there is an e cam in there. I wouldnt run that bbk either. sexy intake but nothing special unless you have forced induction. have you looked into the trickflow intakes? they match pretty well to the heads you have. edelbrocks will be nice too.

If you are going to garage tune it then swap out the injectors. No need for the 42#s but like said above you could probably get away with just tuning the car to run with them. Sounds like a very nice setup. did he get it dyno's at all? I would be interested in hearing what the numbers are.

This comination was only put togeter 500 miles ago and has never seen dyno time. I would like to see some numbers too. Anyone need a BBK w rails and throttle body?
