New guy with questions

[lizardking]

Hi everyone. So a few months back i decided to bite the bullet and finally buy my dream car. A 1965 mustang fastback. When i got it home i took it apart and have been slowly buying parts for it. It is currently at the body shop getting some body work and paint. i still haven't decided what color. But i am thinking either some shade of blue with the shelby stripes or gun metal grey. it was originally paint code 5.
When i get it back from the shop i plan on redoing the brakes and suspension, both front and rear. i got global west upper control arms. and am thinking of using roller spring perches. It has no ac or power steering.
As for the motor i only know what i was told but the info i got was its a rebuilt hipo 302. with a top loader 4 speed with a lakewood scatter shield. the engine has a crane cam 605 lift with a 294 duration. 13:1 compression ratio .30 over and with aluminum flat top racing pistons. it also had a deep sump oil pan i guess to hold more oil.
What can you tell me about the motor? i plan to get headers and exhaust when i get it back any suggestion. long or short headers. i guess for fitment issues.?
thanks in advance for any help.

Just speculation on my part, but the power plant doesn't sound very streetable. Way too much lift, way too much compression (can't get my mind around 13/1 with flat tops. Heads and/or block must be milled out the wazoo, and valve eyebrows cut in pistons must be really deep. Not a criticism, just a way of suggesting that you verify cam specs and possibly compression before you make any decisions. Just by way of a bit of info, if the motor was represented as a HiPo 302, I don't believe they ever produced such an animal. Overall, the car sounds pretty awesome.
Best,
Al

If you run it as is definitely need the long tube headers. Will be a beast on the street though... And you will not be running pump gas with that compression.

Someone either lied to you or didn't have a clue about that motor. I have pop ups in my 5.0 with Twisted Wedge heads and I'm only at 10:1. If that really is the cam, that sounds too radical to put on a street car. Not only long tubes, but a 4:56 gear to get it up in the torque curve quicker too.
I'd start asking for receipts of the build or photos of pistons, etc...
The later 302's, AKA: 5.0 is known as the HO for High Output, but the only HiPo Ford ever produced was the 289.
Sounds like you have a good plan on the suspension though.

You want to GET headers for it? What's it got on it NOW With 13.0:1 CR surely it doesn't have stock manifolds?

You can get a fairly decent idea of dynamic compression ratio from a cranking compression test, but it's always nice to know EXACTLY what you have for internals and to see what head work has been done so that you can pick the right stuff without guessing.

thanks for the input guys. Right now there are just exhaust manifolds on the car. Somebody told me that they are off a 69 302 mustang. But i know its hitting the zbar and actually knocked it loose while at the shop. I read somewhere i can get a clutch cable from mustang steve to replace the current zbar setup?
I think my motor is a 289 made into a 302. I guess the best thing to do is take it to a shop and have them check for me exactly what i have under the hood and then come up with a game plan.
I read that if the compression is that high i might have starter problems as well and there is the entire issue of gas as well.
