I have a 350 bored .030 over engine I can't seem to identify as to what specific year it is.

The stamped block numbers I've found are. (14093638 - on the rear of block) and (V1219TPF on the front block pad.) I can't find information on the TPF in the pad number.

 

That block was used from 1986-1995. One piece seal right hand dip stick and some were set up for a roller cam, most were just a truck motor with a flat tapped cam.

 

It has flat tappets and 4 bolt mains. Do any of these stamped numbers tell what specific year the engine is?

 

Are you looking for a specific year of this motor. They are all the same except for some being set up for hyd roller cams. The block will have three raised humps in the middle of the block where the spider gets bolted to. Some are drilled and some I have seen are not drilled.

 

PM sent.

 

V1219TPF...
V = Flint engine plant
12 = December
19 = Day of month (19th)
T = Truck engine. I did find one source that said TPF is from a 1989 Chevy/GMC 1500-3500 series, 2 & 4wd.
Also look at the bellhousing flange for the casting date to verify, either on the passenger side or middle of the block. Since new car/truck models come out around August, a December engine assembly date for a 1989 model year vehicle, would have a 1988 casting date.

 

I believe you just confirmed what this is. Yes, I see the cast numbers in the outside center of the block but wasn't sure if that was the casting date code or not. It has 638 stamped in the center of the block on both sides.

My brother is wanting to use a set of 305 (14022601) heads with the factory 1.79/1.5 valves on this 350 .030 over block with a carburetor in a 1984 1500. I think it may have flow issues when the engine is spooled up. I'm helping him with this build however I've always built and owned Ford BB engines myself so I didn't know how GM coded their engines.

I really appreciate you guys help, thanks!

 

He's wanting low end torque for pulling but at the same time he needs mid-range power. His truck is a 1984 2x4 1500 automatic and has a factory 305 cid with a carburetor but I don't know what rear end gears it has yet. He's wanting to use a separate set of 305 heads (14022601) that he had resurfaced & worked several year ago.

The original 305 that is still in the truck has a lower end knock and gazillion miles on it so he's changing the engine out.

 

The 601 casting is a 305 HO head and has the larger valves for a 305 motor. Intake are 1.84 and the ehx. are 1.5 like any SB head. Chambers are 58cc and will raise the compression about 1.5 points if the old motor has dished pistons. One other thing you will need to do with the heads is to lay back the sharp edges around the combustion chamber so you don't get some hot spots. You are going from a smaller bore to a larger bore so the edges hang over the piston. Do block off the hole in the middle of the head or you will have run on when you turn the key off. I have done lots of these heads on 350 blocks to raise the compression on hobby stock motors for dirt racing. Only way to do it on the cheap. Don't go to big on the cam with the truck, the thing is HEAVY so you need more low end torque.

 

Great advice and I've just went to the shop and checked the 601 heads myself and they do have 1.84/1.5 valves. I was actually wondering if a stock cam would be enough low end torque and he could keep his new springs the machine shop installed on the 305 HO heads.

The 350 block is a 4 bolt main which of course is not necessary for this application. It has .030 pistons and the rod & mains are standard however this crank is going to have to be ground, the journals have been scored.
