    Glad I could help. The '68 is a great looking car if you get the stance right. Good luck going forward.
  2. '68 Skylark Convertible

    Comment by 'jhodgson' in item ''68 Skylark Convertible'

    I used Year One 17" Magnum wheels on my '68 Skylark. 8" front and 9" rear both with their standard offset. I run Nitto 225-50ZR-17's front and 255-45ZR-17's rear. I had to machine a bolt in adapter to accept the reproduction Buick center caps. I have about 3/4" clearance between the rear...

    200R4 transmission swap

    I did this to a '68 Skylark about 2 years ago. Pretty straight forward. Overall the Turbine 300 (Buick Power Glide) and the 2004R are the same length. So the drive shaft length doesn't change. The transmission tail shaft mount pad on 2004R and the THM400 are the same distance aft of the...

    350 oiling system modifications

    OK here are some more questions. When I got the timing chain cover cleaned up I found that it was cracked along with the oil pump end plate where the filter attaches. I have a chain cover and a couple of pump end plates left over from a V6 project from several years ago. The Timing chain...

    350 oiling system modifications

    Thank you Todd. The serial is 45G126695 so it is a 1975. Good info.

    350 oiling system modifications

    Very interesting. Thanks. It was a few years ago when I built the original 350 from my 68 Skylark. I can't remember there being a windage tray on that engine. I am pretty confident that it was the original engine. It was a cast rocker oiling thru the shaft red engine. Go figure. And if...

    350 oiling system modifications

    OK here is another question. When I built my 1968 350 there was no windage tray in the engine. Nor were there any mounting bosses to put one in. The block I am working on now has no provisions for one either. I think the one I have now is a 1975. Casting numbers as follows: Block 241748...

    350 oiling system modifications

    Thanks Larry. System wise they are identical. Most of what I've found specific for the 350 matches the Jim Weise post except some of the holes are smaller. 1/2" vs 5/8" and 5/16" vs 11/32".

    350 oiling system modifications

    I may have just answered my own question. The feed to the #1 main is already 7/16" so there is no need to change it. #2, 3 & 4 are 9/32" which I opened up to 5/16". Number 1 feeds one rod bearing. 2, 3, and 4 feed 2 rod bearings each. Number 5 feeds only one rod so I'm assuming since it...

    I agree with your cam bearing assessment. For me TA grooved bearings are a given. And like you I am curious about the #5 main feed. This will be another street/strip engine, so I’d rather make unnecessary modifications now than wish I had later.

    350 oiling system modifications

    I am beginning to build another 350. This time, since I have a well equipped machine shop in my garage, I am doing the block prep myself. I have a couple of questions. Most of the published advice says to open the main bearing feeds to 5/16" on numbers 2, 3 and 4. Does anybody know why not...

    I may be a repeat offender. I am beginning to build another 350.

    Small block exhaust manifolds

    I just learned something that might be useful. I am reinstalling a 1968 350 in my 1968 Skylark. I am using the 2-1/2 inch TA Performance down pipe. Due to other modifications, I am not using the stove nor the heat riser valve so I gutted the valve, plugged the shaft hole and bolted it to the...
