4th Gen BBC Project by ulakovic22

Someone was asking about carb pad to cowl clearance so here ya go. This is without an intake gasket, I had it all together to mark the intake ports and took this picture after I took it apart to ship off. Took some other random pictures.

I found out with the Griffin radiator I'm running I can't use the stock plastic support so I need some universal radiator mounts. Anyone sell some or do people just fabricate their own?

It's a standard deck BBC (9.8), not a tall deck (10.2). That's actually why I didn't put a Pontiac (10.25 IIRC) motor in there. You're right, the motor doesn't even look to be shoehorned in there, but there still isn't much room. The whole plan was to take a LT1 car and swap a BBC in there. Mechanically without the A/C everything has been a direct bolt in with no issues other than the driveshaft. The big expense comes from the motor itself and then upgrading the other components to match. Anyway here are a couple of the mock up pictures showing the headers and shaft.

Made a bone head move and forgot to install the oil pump driveshaft, so I had to drop the pan and pump to put that on. Got lucky and the tall valve covers fit, but just barely. Still need to figure out what I'm going to do for a radiator support. Ordering pushrods and new link bars, Comp supplied std. link bars instead of offset ones. Headers going on next weekend and should have the intake manifold back from getting ported in a couple weeks. Then comes fuel lines, brake lines and electrical.

Waiting on the intake to get back from porting and I'm measuring for pushrods again this weekend to make sure I get the right length. After that the motor can be button'd up. Then it's headers and exhaust followed up by a lot of electrical work. I have to rewire the whole car including gauges and the BS3. I would say I have at least until the end of July since I only work on it during the weekend. That's also only if my parents don't have a list of stuff that needs fixing when I go out there. Last weekend I had to put my Dad's riding lawnmower back together before I started working on my car, lol.

Ok been a while since I posted. Got the intake manifold back, ordered pushrods after measuring and new link bars for the lifters. Come to find out as I was putting everything together that one of the lifters at the base of the cutaway was bent and when put together with the link bar wouldn't slide into the lifter bore so I have to get a new one from Comp. Pictures below show the bend and also you can see the crack on one side of it. In the blurry picture you can kind of see the highlighted cracks on both the top and bottom.

Still working on the headers. They no longer bolt up with the RHS heads like they did when I mocked up with the stock 990's. Hitting the k-member really bad so I'll have to relief cut them and bend them up so they will fit. I'm so glad they were only $150, lol. Eventually I'll get a set made, but I'm not at the point yet where I say screw it and buy a $1300 set of headers.

To minimize down time I ordered a single lifter from Jegs and then when Comp sends the replacement I would just return that to Jegs. Well today I got the replacement and well I'm just kinda ticked. I ordered an 888-1 which should be a single lifter of the 888-16 set I had ordered. Instead I got this, the lifter on the left. I'm not sure exactly what happened but obviously the lifter on the left isn't a HIPPO lifter like the other 15 I have. Guess I have to wait another week or so for Comp to get back with me about the cracked one I sent back to them cause these lifters are still on back order everywhere.
