Keep the LT95, you can't destroy it if you tried. Find an overdrive for it in the UK, they are very robust..

http://www.ebay.co.uk/itm/LAND-ROVER...item4d00d96b76

Since you have an edelbrock, go with one of these...

http://www.ebay.com/itm/Holley-Pro-J...d6a419&vxp=mtr

use an buick HEI distributor...

http://www.ebay.com/itm/Buick-V8-215...ed2e33&vxp=mtr

It'll crank with a touch of the key, hot or cold, next day or after sitting 6 months.....no choke, no Lucas electronics, no brainer!

Your set up is a multi-piece y-pipe that goes over the square removable crossmember, right? I agree with the recommendation to fit the RRC angled cross and even if you don't need the cats, you could have a muffler shop remove the cats and fit straight pipse. The advantage would be much easier service and most likely intereference free routing of the exhaust.
We recently fitted EFI toa 3.5 and and fit a 3.9 into a 3.5 car with carbs. The 3.9 carb also included the R380 and LT230. Fiddly stuff like driveshaft brake heater pipes, seemed to take longer than we expected.
Seems like your least expensive route is to just fit the 3.9.

The overdrive is a nice option for down the road.

The pro-jection would be fun down the road to.

A quick question on the HEI distributor, does it have to be a buick one or would a 350 olds distributor work as well. I have a rebuilt one laying about that I could use and had been planning to try it when I swapped the motors.

Trevor, I think your correct on the y-pipe assembly set up. I'll have to crawl underneath to check to be positive.

I think I'll just leave the LT95 alone till the summer.

Check in with Will Tillery. He's sure to have something you can use.

Also, i have a Pertonix v8 electronic distributor, almost new,( not for fuel injection) if you want to add that to your upgrades.

If you have an older 3.5, the oil pump connection to the dizzy will be backwards from buick (male/female reversed), that's no problem, however, all you have to do is swap out oil pump gears for a 3.8 Buick V-6 (dirt cheap) and the HEI will mate up. And high volume gears are only a few bucks more.

Also don't you have to clearance the intake manifold to fit the HEI distributor?

Yeah, you have to grind a little material off of one of the runners on the Edelbrock for it to fit. No biggie.

If you are using a 1991 3.9, or a disco 4.0(switched to the distributor setup) with a carb do you need to change the oil pump gears or is it just grinding the manifold then?

If that's the case the HEI comes out a bit cheaper than the petronix and has better parts availability. So that seems like a good upgrade to do.

I've been looking at cams at it seems like it would be a decent idea to do a upgrade on the cam for a bit more power while I'm in there. Any recommendations for a bit more power without getting to crazy?

The oil pump is part of the front cover. If you use a disco 4.0 you will need to change the front cover so you can use a distributor so you will also be changing the oil pump.

But if he uses a disco 3.9 then he can run a serp belt.

Finding a serp belt for a alt and ps pump only would be interesting

Clarence, such is life. We'll see what Brett and I can work out on that 4.0.

So the 229 or the 230 seem to be good choices for the cam. I'm just looking for a bit more power without going crazy, thoughts?

You can use a 4.0, there was a front cover called the "intermediate" cover that allowed the use of the newer block with the crank driven oil pump with a distributor. I think it was used only a year or so on the 4.2's.

On the cam, if you don't want to spend the money, you can use an aftermarket adjustable timing chain set designed for the 3.8 buick. (which I would use regardless over the factory timing set anyway, much more robust). Advancing the cam 3 degrees with the adjustable timing chain set will give you basically the same cam profile as a 4.6 cam or an aftermarket cam.

I built a 3.5 from the ground up, bored it .030 over. Only parts I got from the UK were pistons, rings, main bearings, cam bearings, 4.6 valves, and gasket set. Rod bearings, front cover, timing chain were 3.8 Buick. Edelbrock mani, Heddman headers, HEI dizzy, and Holley Projection. Ported and polished the heads with a Dremel. Would blow any stock 4.6 away.

I thought the covers pretty much interchanged from the 3.5 to the 4.6 with no real issues, am I mistaken?

You can use the front cover, heads, manifolds etc from your 3.5 on a 4.0 or 4.6. The front of the crankshaft is longer on the later engines so you either need to make a spacer out of an old timing gear or purchase one. It just takes up the space between the bolt and the pully. If you use a later non-dizzy engiine you will have to change the cam but I would suggest doing that on a used engine anyway.
