This is still a perplexing issue. It is the gas we have to use. It's different in the summer from the winter, north to south and around the world. The combustion chamber is really the determining...

Yup, 263 and 248 heads are one & the same. There are differences in the decks that are worth noting. The bolt holes are in the same place on both engines (obviously) but the cylinders are not. The...
This subject has been kicked around quite a bit here on team buick as to which is the better engine as well as all the "problems" that each engine has in reguards to performance building. You need to...
Allright Dave!! You got the 39 back into the land of the living! What did you have to do to get it there? I just got back to Fallbrook about 3 weeks ago, I'll have to drop by and have a look-see when...
The engine you have is a 1948, possibly a 49, 248 out of a Special. What dates it as a 48 is the side mounts on the block which came into use in 48. Prior to the side mounts all str8's used the front...
After thinking a little bit, this could be a early 263 and the 1950 263 had the best rods in it. You may want to go back and pull the rods as well. The early rods are VERY hard to get and if you want...
This is certainly a bit odd, the boys at Buick did the bottom end of the 263 (the whole engine for that matter) to be "moderen" and do away with shiming the bottom end to get a correct fit. I've...
Boy, do I like that coupe, it'sa Buick. All I need to know! My knowledge is mostly in the later engines but since they are closely based in the earlyer engines, a lot of tricks go both ways. Ill help...
I'm going to throw in my 2-bits here as well! The gasoline that we have now and the gasoline we use to have back in the 60's is completely different stuff. The gas back in the 60's, both regular and...
I'll get back to you in a bit, kinda up to my ears with stuff right now! alleycat
It's my understanding that in the 1970's there was a fire in Buicks records area/department? and that all records prior to that date were destroyed. So, unless there is some numbers in a Hollanders...
I got 61 pistons from egge, totaly as cast. I have run all of them through the lathe and got them all "round" so as to determine what oversizes I can get out of them. These things are cast hugely...
All the heads are the same. However, some time in the late 40's, into the 50's, buick moved the spark plug about 1/4" into the chamber. In order to do this they put a little boss around the plug...
Back up to nali's #6 post, he included 2 photos, you may have to "open" them, the bottom photo shows the ribs. alleycat
Dale, I think I know what your problem is, almost exactly the same thing happened to my 248 once apon a time. About 30 years ago, I put a supercharger on my 248. I ran it around town for a while and...
I'm still out here! However, I've not been able to do much work on any of my car type projects. House projects MUST be done befor winter sets in, my shop must be upgraded in order to do some of these...
Oooh! A finger smash! That ALWAYS got my attention. Did it many times. On to the bearings...Buick always did use very close bearing clearance, which I like, but no filter and oil "out of the ground"...
I don't know exactly what babbit alloy is in the rods but "soft" is kinda a relative term. Clevite 77 insert bearings are "soft", were as Michigan bearin gs are "hard". The clevites have a higher...
You will very likely find not much or any ridge in the block. The rings and then the pistons would start to self destruct at about 60,000, which is likely the reason for the low comp. Believe it or...
Bob is totaly correct. There was no 263 in 1938. This engine may have been in a 38 for a while, but it did'ent come in it. This 263 most likely started life in a 1950 Super.
The dead giveaway that...
Basicly, all 320's are the same engine. But at about 47-8 things started to change. Buick was going to introduce the 263 in the then totaly new Super for 1940. This engine "fixed" every problem the...
Without a doubt, it is a 263. It also looks to be a 1950, the very best one you could have got your hands on! Congrats! alleycat
Yes, I've heard the "if you replace the rod bolts, then the rod must be resized" story as well. When I got into racing back in the 80's (sounds like a long time ago, don't it?), I was doing a set of...
ebbsspeed, don't let anybody touch those rods untill you check a few things! Do not believe the old storys like; " well, they've been in there for 50+ years, how good do you think they are?" or "it's...
Is a h.p./inch possiable out of a str8 Buick? I think so. In fact, I think it has already been done. By some of the "old" racers that post here from time to time and some of the guys that are...
