So all the builds and swaps I've read about with 4BTs into Jeeps require Long Arm suspension since the upper control arm gets in the way of the starter.

There in lies my problem. I want to go the 4BT swap in my ZJ but I'm not ready for long arms just yet. I'm wondering if anyone knows a way around this issue?

You could try to leave the oil pan forward, may clear. But remember, The 4BT is a very tall motor.:dustin:

I'm not against raising the engine to fit it without long arms (could even fab a cowl of sorts if needed).

I did not use a long arm kit but raised the engine and also used a starter from a case setup I think I have a pic on my page
Found the picture, happen to have a part #?

I've got a 3.5" lift here, ready to go on the truck. I think it could work.

Alright, found some info that I'm gonna share.
First is the engine bay measurements.
Firewall to Rad: 33.25"
Motor mount to motor mount: 27"
Firewall to Rad. Support: 38"
Frame Rail to Top of motor: 21"
Oil pan to axle clearance (guessitimate because I couldn't crawl under to measure): 5-6"

Found some Engine dimensions for the 318:
A = 29.50 B = 29.50 C = 23.50 D = 31.00 E = 25.00

A - Length from rear of intake manifold to water pump pulley
B - Length from rear mounting surface to water pump pulley
C - Height from bottom of sump to highest point of intake manifold
D - Height from bottom of sump to top of carburetor
E - Width outside of valve cover to outside of valve cover

IIRC if you use a Ford FW housing and starter (left side) combined with the 7* tilt of the engine it will clear the upper CA mount. I know of one guy who did the GM FW housing, and starter( right side), and AX-15 in a TJ and he was able to use the stock CA upper mounts. In my TJ it would not fit so I went with LCA and Poly Perf. mounts. I am using GM FW housing, starter and TH400 trans.
So I guess in short it all depends, there is no solid rule on the upper CA mounts.

Yea, I think it depends on a lot.
Going to use an NV4500 with my swap.

Think I might just say screw it and work some over time so I can buy Long Arms.
