check'd with our sister store (gm) and had him look these up . 68-74 350 , the original part number supercedes up to part #12337249 ( 4.1 v6 14 bolt oil pan ) . is this correct or is there other info out there . my 4.1 covers that i have seem to have a noticably larger oil delivery hole in them than my 69 350 covers do . my price was not tooooo bad and all the covers that i have now are 50/50 at best . what's everbody paying for these ? if these are an ok deal and if a few of you need them i may be able to talk him into a deal plus shipping of course . i just am not trusting the ones i have . is the casting quality better than the last 455 cover i got a few years ago ? thanks for any info . del
The v-6 covers are fine for the 350. They are realtively cheap, very available, and do have larger internal passages. Jim Burek
The V6 cover worked great on mine......you'll have to do something with the timing mark though, as mine did not have one like the 350 cover had. I think I paid $99 for mine. Mike
Yes I used one from a v-6 also. Cost just under a 100 at Pacific Automotive Warehouse. Only problem. No timing indicator
350 covers jim : any big differences in cast quality between the gm and aftermarket units ? and should the block oil passages be opened up to match the cover similar to the big block procedure ? thanks for any info or ideas . del
Re: 350 covers I open the block passages up on the 350's to 1/2 inch on the suction side. It's a good idea to open the feed hole in the block from the cover. The 350 does not need quite the volume of a 455. We do kind of the same things on a performance 350 as we do on a 455, Just not as big on the passages. Side note, these aftermarket covers require the use of a timing tab still available trough GM, same as the v-6 engine. SO far, I've been very pleased with all the ones I've bought, I have used several different sources. Jim Burek
I got my V6 cover through GM 14 years ago, had to get the timing mark tab also, it's still there, working like a champ, 14 years and 175,000 miles later!
350 covers i ended up ordering one from our sister gm store . $153.00 ( employee price ) for a new one - comes with gaskets apparently but thats it , a new cover woulda' been nice . i think the TA covers ( or whoever ) that are all set up and ready to go are fine , a little piece of mind for a higher dollar motor owner . one less thing to go wrong . if you are spending 4-5-$6000 on just a motor , no sense having it "wad-up" on you because you tried to save a couple hundred bucks on an important part of the package . would you install the $150.00 pistons ? those prices may sound high but years of racing/street time and expierence and learning from mistakes costs them money and saves you money . be wary of the local garage that says he can throw one together just as well for alot less money , not that there isn't some out there that can do that . theres a big difference between putting one together and "building" one . del
