67' Belvedere II restoration

[67'Plyman]

I need the front grill, clip, bumper, right fender, and other misc parts to really do this right. But my biggest issue is, what mounts do I need to put a 78' 400 in where my 318 currently lies? Also, does anyone know where I can get a front disc set up from a GTX? Theres nothing around me from what I've seen. I'd like to at least have front disc's on my car when I'm putting a big block in it. Otherwise I'll just end up doing a full conversion on it later. Also, If anyone has any information on the interceptor engines, that would be greatly appreciated since the 400 I'm putting in is out a Newport Interceptor.

When I installed my 383 in the Belvedere, I used a set of big block motor mounts from a 70 B body and they dropped right on the stock small block K member. I would think brackets from a 66-70 B/E body would work fine. As for a disc brake conversion there have been lots of posts on this subject, you can search the site for"disc brake conversion" and find lots of info. You can also click on this link for some good info. Good luck and lets see some pics of what your working on.

Not to rain on your parade, but there's no such thing as an "interceptor" engine in the 60's and 70's Mopar world. I've never heard of a Chrysler Newport police car either.

Most non-HP motors were somewhere in the 8.3-8.5:1 compression range.
Most HP (high performance) motors were in the 9.5-10:1 range.

I believe all 400s are 8.x:1

This has helped them earn a less than favorable reputation for "as delivered" performance. If you can do something to get the compression up, they can be screamers.

There is a VIN code for police class cars. I believe it is "K".
For example say you had a 1970 Coronet police car- The VIN might be WK41N0G999999
W- Coronet
K- Police
41- 4 door
N- 383 HP engine (same engine as Super Bee) (could also be L code 2 bbl)
0-1970

I also believe that all 400 engines, wheather 2 or 4 barrel, had the same 8.x:1 compression.
