You might want to beef up your tranny, rear end, brakes, and sub frame while your at it. Those engines pack a good punch!

A 502 is no different than any other short deck BBC swap.

Re: 502 ramjet
no need to bolt the 700r4 up to that 502 although yea it would fit but you would have to pull it out and replace it no sooner than you got it in.

2500 would be adequate for most usages. What do you plan to do with the car?

It's a little difficult to hide a 502 Ram Jet in a 3rd gen.

Re: 502 ramjet
I bought a 502 ram jet to put in a 91 trans am, I was thinking about supercharging the zz383 but I have change my mind
Anyhow, I know that I will not have trouble to fit the engine (exept the hood), I was planning on do some mods that I want to ask you people for the make the right mod.
1) 8 point Roll cage (but I need to get in and out easily from the car) (compettition engineering or spohn)
2) Which housing for the rear end? Which is better for street and track (4.11, 3.90, 3.73, I want to accelerate fast)(moser 9" or compettition engineering
3) K member or not to K member
4) TKO-600 but where is the best place to get it?
5)I will swap rear drums to disks, should I change my master cylinder? I will use wilwood 12.6" setup.
6) I have spohn sub frames, lower control arms, wonder bar, and torque arm, should I replace them with an other brand or should are they(spohn) reliable?
7) I have tokiko struts and moog springs when I put the 502, do I need to replace the front springs??
Only these questions come to my mind for now
Thank you for your time...
