I know where there is a TH-350 for free, but it needs a short tail shaft and tail shaft housing (came out of a 4wd)

Y'all aint going to believe this! I couldnt help it, couldnt leave it alone. all i had in a spray can was silicone so i decided flip the engine upside down and hit the cylinders from the back side. 3 whole turns and you can still see the crosshatch in the cylinders! Would never thought it! going to break this puppy down in the morning and put a hone to it and see what all cleans up.

That video brought back some old memories. My first street car was a 62 Chevy11, 194 with 3 on the tree, and a 4 door besides. Had the chance to buy a 67 283 2 barrel engine from a wrecked Nova, got the frame mounts and crossover pipe with it. It was a direct bolt in swap, cut the 6cyl exhaust pipe and it hooked up to the crossover, used the 6cyl clutch and flywheel also. Most fun car I ever had, with the 6 drive trains gearing it would hole shot most anything around, sure did surprise a lot of big motor Mustangs and Mopars.

well all apart, and everything is borderline. crank may come thru with just a polish, but if not there is plenty of meat on the bone! same with the cylinders, they may hone out but not with my had held hone in a drill. very little if any wear on this engine, it just got wet. just about all of the rings are stuck, not going to put much time in there yet because if it needs bored that would just be a waste of time trying to free them up! guess its off to the machine shop next, I got a good machine shop. he is honest for one, if it dont need bored or the crank turned he will tell me. Not like a lot of shops that will tell you it needs it when it dont!

got one head broke down today, It needs two intake valves right off the bat! stems are almost rusted into. guides feel worn out too. but they appear buildable. I may just replace the rocker studs with threaded in ones, I have been down that road! never had one work out but have had one break on the wifes car years ago and it was low miles too 44k when we bought it. makes me wonder if she may have been hot dogging it! LOL! I highly doubt she was. but just maybe?!

I know i have been lax on pictures in the past, and about to do so again! so i decided i had better get some took, I will take a few after shots after i post these. these are in no particular order. Intake valves are not going to make it, they are rust pitted badly!

2.02" Intakes. I was just looking at the numbers one was made december 5 1965 & the other was made december 6 1965. pretty sure these are the 461 heads. looks like if i want the L79 power i am going to have to up the compression a tad. My book calls for 11-1

This is probably going to be a slow build so i may take the time to do a port & polish job and if i can talk the machine shop into it a 5 angle valve job.

No more than you're doing with it, a 3 angle will suffice. And don't go overboard porting. You can do more harm than good. .

Given what passes for "gasoline" these days, I advise somewhat less than 11 to 1 compression if you plan on using pump gas.

The 151 cam has 0.447/0.447 lift, 290/290 advertised, and 222/222 at 0.050

curious just when gas went to crap? The last one of these i built was around 10-1 compression and ran fine on 87 pump gas, unless you lugged it. if you lugged it it would let you know it was not happy! I ran that engine up to around 04 i believe. still got it too!

Hot Rod, Another popular cam in my youth was the 30 30 Duntov Bet I mis-spelled it. You got the specs on it?
