Pedal Box or similar
 
Has anyone had any luck using a Pedal Box or some other means to relocate or eliminate the FB (83 Rx-7 to be specific) Power brake booster, master cylinder, slave cylinder etc.

I'm anticipating some challenges stuffing a 351C (351 Cleveland) into an 83 Rx-7 wide body I have. On a 5.0 or 302 the heads barely miss the brake booster etc. and with the 351 Cleveland being wider than both the 302 and 351 Windsor engines I'd just as soon relocate or use a Pedal Box.

Any input would be appreciated on brake booster etc. relocation or a good Pedal Box or similar set up.

Thanks!

Thanks I really appreciate pointing me in the right direction. This will be my 4th V8 Rx-7 and the others had Ford 5.0 or 302 conversions. One of the things I've noticed in the engine conversions is how everything in the driver's side corner of the firewall that is brake related gets within inches of the valve covers and exhaust.

I recently rebuilt a 2V 351 Cleveland and am getting ready to paint it. A 4V 351 Cleveland 408 stroker is the next engine I'm going to build. I have been eyeing my 83 wide body and thought this would be a good time to get input. Before doing things the way I think they might be done, I was hoping to get input from someone that has already done it or knows someone that has.

When I spoke to the gentleman that owns Grannys speedshop (I can't think of his name right now) He couldn't think of any reason a 351 Cleveland wouldn't fit. I have a foxbody oil pan, mounts and anything else I can think of to do the swap. The remaining challenge is going to be relocating or replacing everything associated with brakes in that corner of the firewall.

Here's a coupe pics of one of the Ford 302 V8 conversions I did. You can see where the brake booster etc. will more than likely interfere with valve covers and headers on a 351 Cleveland, especially with tall valve covers for roller rockers.

The other side has room for days.

Thanks again for the valuable input!

That is an excellent alternative to some of the other options I've been looking at. Thank you Freeskier7791 for the link I really appreciate it.

No problem, good luck with the build
