My 305 is shot in my 91 Camaro and i have available a crate 307 with about 10,000 miles available. I want to drop it in because i have it and it runs great.

I swapped over accessories, I have a new intake manifold to mount the TPI and have provisioned to ensure i can maintain all emission controls. I've run into a problem I didn't anticipate...the dip stick is in a different location and I want to use the stock exhaust manifolds to avoid having to do a custom exhaust at this point. Plus it maintains the provisions for the factory A.I.R. system.

Anyone aware of an alternative approach for supporting the dipstick? Ever heard of an oil pan that the dip stick can connect to directly? Even the 305/350 goes through the block although very slightly. I'm surprised a bit because I always thought the blocks for the SBC where largely the same except for a few changes in the 80's changing bolt angles on the intake and headers for example.

Now I know this isn't a common swap to make and some would say "why?"...all fair questions

Has nothing to do with "307", 305, 350, or any of that.

Your manifolds simply will not work with the stock early-model dipstick arrangement. Period, paragraph, end.

There is only one oil pan that I know of that will work, and AFAIK it is LONG discontinued. Certain A & G bodies in about 77 and 78 came with it. I had a 78 El Camino that had is, for example. AFAIK GM sold out of it some decades ago. Last time I bought one of those was in the early 90s, and it took a major scouring of the Earth to find it even back then. The "gauge and tube assembly" was even tougher. Not likely you'll come up with that today.

Best choice nowadays, is an aftermarket setup such as Lokar, with the flexible tubing section.

Or of course, what any sensible person would do instead of fiddling with the manifold crap, which is, get rid of the manifolds and replace with headers.

Thanks - as I fiddled more with it after posting I realized additional problems as you mentioned.

I thought about headers but I was hesitant it would effect emissions and I'm a couple years away from North Texas not doing the emissions test. I'm nervous about putting in all this work and not having it pass. Should I be that concerned? How much does the AIR system play into emissions control? Maybe I'm really stressing about nothing.

The left hand dipstick can be finagled to work with the stock manifold. It requires flattening the dipstick tube and grinding a little off the back of the manifold header where the dipstick will pass between it and the head. Got that advice from Damon somewhere and applied it to my 85 which has the L69 exhaust.

Here is one way to make it work...

Buy a K-Line KL9670 adapter off ebay.

Buy this oil pan from summit

Use your dipstick and tube.

Sure it sounds simple... But you will have to drill and tap two holes which require the right tools and skill. You may all ready have that!
