Would I be able to put a 1977 transam 400 into a 1967 firebird as a direct bolt in? What would I need to use for the engine and frame mounts? I appreciate the help. I know this is not a real desirable engine but I am looking for a running low compression pump gas friendly pontiac v-8 that we can have sound good and be reliable. Were not going for a high dollar high performance pontiac enigne. I am trying to bolt something in to where the engine will bolt up at factory locations so I can have the z-bar pivot in the correct location, along with the shifter coming out in the correct tunnel opening. I may go automatic first and eventually use the muncie trans and hurst shifter/linkage that I have stored away. Any advice is appreciated. Jeff

The frame mounts will be the same as a correct year Pontiac V8, but the engine mounts (use the mounts for '68 Bonneville) may need adapter plates depending on your new block.

Five bolt hole per side blocks should not need adapters. Three hole blocks will. I don't have a name offhand, but most of the Pontiac performance vendors (Butler etc.) will have adapter mounts.

My former '68 had home made adapter plates, I had no issues with them.

So it is defintely possible to bolt right in. Thank you very much....I may consider a trade with this guy for my OHC6 engines for his 400 complete. Jeff

Bear in mind, the later castings (like 1975 and on) a said to be a little weaker. Fine for mild applications.

No this would not be a bolt right in.

You will need adapter plates as Vikki mentioned. Bolt right in would be just that, bolt right in and go. You may want to search for an earlier 400 as the hp ratings are extrememly low after 70...

My bad....What I meant was with adaptor plates I can purchase off the shelf mounts that will drop this engine in the correct location. I just didn't want to fabricate some custom mounts. Thanks jeff

You will need V-8 frame mounts if you are changing over from a 6 cylinder. They are readily available, and there is a good market for OHC frame mounts.

Unfortunately my car came without an engine or transmission and someone had welded in small block chevy mounts from god knows what year car. It was quite a mess. I don't know why they didn't get the correct mounts to make the small block fit right. I aquired one sprint engine and one ohc6 single barrel engine that I am going to try and sell locally. I would like to find an early 350 pontiac or 400 that I could pick up complete in the seattle/portland area. I am keeping my eyes open. Thanks for the advice! Jeff

I have a complete '67 400 2bbl. Excellent low mileage engine, excellent never bored core. Complete pan to carb, accessories too if needed (alternator, PS, pullies).

The cammer engines are a lot of fun. You might want to give the Sprint a try. The car feels ligher and more nimble in corners with less weight up front.

I wish you were not in Michigan. That 400 engine sounds right up my alley. I am going to go look at a 1974 Pontiac 350 engine that is suppose to be complete. Same guy that is interested in trading for my OHC stuff. I like the idea of this route since thier are no adaptors involved. My understanding is the 350 and up pontiacs pretty much look the same? Hopefully Wednesday I will make my way up to the guys shop to see what he has got. Jeff

Hey Jeff, saw your add on CL and was tempted to try to find a way to pick them up and eventually build a sprint-6 again... but lack of space, time and money... you know the story...

Anyway, I'm in the area and have a lot of contacts through the Western Washington Firebird club... I can check around for you if you like, and or if you need reference, you can check out my 67 or my neighbors 68 any time or I can always get you together with a few of the local bird owners...

I'll send out an email on the WWF list and see if anyone has something for a resonable price that is complete.

Talk to you soon - Brett!

Hey Brett, sorry for the slow respond. I have been working six days a week 10hrs a day for about 10 weeks straight now and figuring in my 1.5hr commute my time is scarce lately. I did manage to trade a guy in Bonney Lake my OHC engines for a 1977 Pontiac 400 YU engine. Its only 180hp with 6x #8 heads. The thing I was mainly after was the engine is 100% complete from carb to pan along with alternator and PS pump. I am going to freshen this engine up and try to make it a very mild 400. I bought a brand new delta camshaft that the guy had collected for it too. I don't have the numbers in front of me but it was a mild enough grind for a little bit of overlap for nice choppy idle. I also purchased a performer intake from him that I am going to use too. The 800CFM carburetor it came with will need a spacer plate for the intake since the secondaries won't clear the intake throat to open. I am also in the middle of restoring a 67 Camaro convertible and I am in the final stages of doing full 1/4s, complete trunk floor, innner/outter wheelhouses, and tail panel replacement on it. I want to get my Camaro back to being a driver before I mess with my sons Firebird much more. Its getting messy in the shop having two cars scattered about. My son is only 11 and just now showing interest here and there. I would like to eventually figure out what pistons I could put in this engine to get a 9.5:1 compression ratio with the stock heads. I would like to get as much "performance" as I can from a basically stock pump gas engine without going broke. I am looking for a nice passenger side hood hinge if you know anyone that is selling a spare. I have one but the pivot is all sloppy and causes the hood not to set flush with the fenders and cowl.
