Jeep Wrangler V8 ID
 
1 Attachment(s)
Hi everyone,
I picked up a Jeep a few days ago that has what looks like a small block Chevy V8 and has been converted to a 3 speed automatic.

The trouble is I can't positively ID the engine or transmission. Can anyone help me?

Thanks

Sorry I will post pics of the engine when I get to where the Jeep is parked this weekend.

But I guess more specifically my question is where to look for identifying numbers to ID the engine.

Right side of block. In front of the head there is a "pad" that is part of the block. There will be letters and numbers stamped in that pad. Get those numbers off of that pad.

This pad will be, like I said passenger side right in front of the head, if you had the head off it would be at the end of the cylinders in the block. Does that make sense?

I think so... I will get to the Jeep possibly Friday evening and take a look and snap some pics. Thanks.

Did a little searching and came across this. This will decode the casting numbers for your motor the last three letters of the top one is what you put in. The bottom numbers is the partial vin for the motor.
CHEVY Mania!
This site will give you a little more info on decoding it.

And yes I will clean and degrease it tomorrow. :)

You might want to also get that plug wire off that exhaust manifold before it burns it.

shadowbethesda 08-02-2013 04:59 PM

lol that would be good wouldn't it? :doh:

Cashcrazy 08-02-2013 06:18 PM

Looks like a 305 or 350. They are basically the same block with the 305 having a smaller bore. IIRC the 350 had a 4" bore. there is plenty of info on google for identifying those.The question is what trans/tcase did they use?? Ill take a guess... Th350/np208. Take a shot of those. The tcase will have a tag on it probably and again plenty of info on those chevy products.

rykemc 08-02-2013 07:06 PM

It is not a tag but part of the block that will have letters and numbers stamped in it. Right in front of the passenger side cylinder head. You will most likely have to remove your alternator and possibly the bracket if it bolts to the end of the head.

kywaterman 08-02-2013 10:16 PM

It'll be a flat spot right in front of where the passenger side head bolts on. The engraved numbers may be covered in paint so might have to scrape around to see them.
Go to this link and it shows the spot. How to decode Chevy Engine Codes
Looks good a little cleaning and and tune up and it'll look real good. get some pictures of the rest of the drivetrain and we might can tell you some about them

Take a pic of the balancer, if its the small balancer, its a 5.0L, if its the bigger one, its a 5.7L, however that IS an older engine and it could be a 327 or 400, with an HEI conversion (very easy as HEI is GM smallblock native, one wire hookup upgrade).
The tag in your second picture looks like a re-builders marking for machining (Old School), how much was cut from crank, piston bore and deck milling information.

Well the casting number indicates that it's a 307. Pics to follow. Thank you for the links guys.

307 was a fairly good motor. put out about 200 hp stock. used in the late 60s early 70s.

A new set of wires, plugs air/oil filter for it are next on the agenda. Then ID'ing the transmission so I can order the appropriate pan gasket (it's leaking).

The automatic gearshift selector is some kind of hokey homemade thing so I ordered a cheap Z-shifter as a replacement (please don't flame me for that I know it's not the greatest but on a budget).

The radiator is ridiculously small for the Jeep as well so a replacement is on the menu as well.

Post a pic of the trans pan, should be easy.

307's normally had a 350 turbo tranny

I will have more pics next weekend when I see it again. I have it parked at a family members house (no more room in my driveway).

1987Wrangler YJ 08-04-2013 07:48 PM

could be the stock tf999 3spd that came in the auto YJ's

shadowbethesda 08-05-2013 05:57 AM

Interesting thought but I wonder... It started off as a 5 speed judging by the clutch pedal that's still in it as well as the manual shift boot.

shadowbethesda 08-09-2013 08:44 PM

Here are pics of the transmission. As soon as I can positively ID the unit I will replace the gasket and filter as well as replacing the missing cover. I'm all ears.
