SN identification
on: Thu 09 of Jul, 2020 [22:57 UTC] score: 0.00
Starting on a project and need help with identification of motors.
I recently picked up 2 vintage Hemi engines. Both have SN stamped on the top rail by the valley cover, But I can not find the numbers listed on any of the SN logs. Wondering if anybody has additional information.
One engine was removed from a 1 1/2 ton Dodge truck and has the number VT 348. Close as I can come up is a VT346 truck motor being a 241 or 270 cid
Second engine was removed from a school bus and has the number B2677. I find very little reference to any numbers of B.
Help would be appreciated.
thanks Rick

>VT 348. 331 Chrysler truck hemi
B2677. The casting number will be on the passenger side between the valley cover & the valve cover twords the back of the engine. B seems to be a weight rating for truck engines.

Nuts, Bolts & Washers
on: Mon 06 of Jul, 2020 [00:09 UTC] score: 0.00
I recently dug out my 241 with intentions of putting it in my 1950 Dodge truck. I've had this motor for about 20 years and I remembered that I didn't have all the parts. Most of what I don't have (exhaust manifolds, starter, distributor, bell housing, generator, fuel pump) I'd probably replace/upgrade anyway. However, I discovered I have very few nuts, bolts, and washers. Things like valley pan, intake and exhaust manifolds, timing chain cover. My question is: does anyone offer a complete nut, bolt, and washer set for these motors? Absent that, what is the best way to determine bolt size, pitch, etc?

Assuming the Dodge is similar to the Chr. The top row of valve covers use studs as does all (?) the exhaust mans. They go into oil or water so you don't want to use bolts there. If no complete kits go to hardware store & buy one of each bolt that looks like the right size, keeping each marked as to size so you know what they are. In case you don't know...The LA dizzy is a direct bolt in. The 241 has an advertised C/R of only 7-7.1:1, but one measured out at only 6.19:1!eek Forged 10:1 pistons is recomended.

George, thanks. I was afraid I would have to spend a lot of time at the hardware store...

Better off going aftermarket with Eagle Crank/Rods or modify a stock unit?

I need to find/replace my crank, what's the best route to go?

Thanks for your help!!!

Eagle has nothing for early Hemi. An outfit called Willys will make you a crank if you supply a core.

I am installing a 392 in a 1967 Barracuda FB. I have a few questions: oil pan, engine mounts, headers, ect. Is there anyone who has installed a 331,354,392 in an A-Body? Thanks John.

A google search will lead to several discussions on this

Seems to me there was a Thread on here about putting one in a Barracuda, but that was years ago. Shouldn't be too big a problem if the engine that came out was center or rear sump.

Alternator relocation - 241
on: Thu 25 of Jun, 2020 [05:50 UTC] score: 0.00
I have a 30 Plymouth with a 241. It ca me with a single wire gm early alternator mounted high above the left head. I want to lower it so it won't block the view of the engine. I got a local armature shop to modify a new gm alternator so the output wire is mounted to the side, not the rear. This allows it to fit low and have the pulleys aligned.

The car came with a Speedway front motor mount. It appears I'll need to fabricate a bracket and weld it to the front motor mount bracket. This would put the swivel point on the bottom and the adjusting bracket above. Hot Heads has a bracket, but I'd have to change the cam, front cover, motor mounts, etc.

Has anybody successfully lowered the alternator on a stock engine? Does anyone make a bracket which would mount to the waterpump housing allowing a top swivel point? Thanks.

Look at the Vintage Hemi Lovers page on Facebook... There are some pictures of different low mount alternators...

My bbc water pump from hot heads needs rebuilding. I understand the rebuild kit is from a 1970 Chevelle big block. My question is ,is it the 396 or the 454 kit I should be looking for. Or are they the same. Thanks Bob

Pretty sure they are the same.
Your auto parts guy should know.

Desoto 341 cam
on: Mon 01 of Jun, 2020 [02:58 UTC] score: 0.00
Hello everyone I'm new here as I recently purchased a desoto 341 hemi for my model a build. I'm wondering if its possible to modify the engine or camshaft in order to use something with a little more lift and duration. I no I can have the original cam reground but that limits what you can do. Any help is appreciated.

Help 330 DeSoto

I have just installed a 1956 330 DeSoto into my gasser. Coolant leaks out from the top valve cover bolts and several exhaust bolts. Is this normal and if so what do you recommend to seal the bolt threads ?

lots of the holes in the block & heads go into water or oil. Mopar used studs on upper valve cover & the ex mans. Put sealer on block side of studs so they don't decide to screw out instead of the nut turning. Some timing cover bolts go into the crankcase, but they don't seem to leak
