Target motors were replacement engines you could buy over the counter at your local GM dealer, short or long IIRC. Don't recall them being corporate blue, but then I only ever put them in PU trucks...

 

All black, complete shortblock + cylinder heads. No?

 

They came out about the time of the switch from blue to black. I seem to think that they were blue for the first year or two.

We put one in a friends 74 Vette in March 1980. You've got me curious. I think his was blue, but now I'll have to pull out my slides of that project and see if it was.

The actual name was "Target Master" and they were a heck of a deal. Brand new 350, fitted block with 4 bolt mains, heads, pan and valve covers for a list price of around $1,000. All you needed was a carb, intake, distributor and water pump. Each motor had a foil label on the valve cover that said "Target Master 350".

 

Yup, but if it's anything like the GM Goodwrench 350 that replaced it, the compression ratio is probably <8:1 with a 76cc head.

 

 

A couple pics for reference regarding pin striping and hood emblem location.

 

VIN - Looked from outside thru the windshield on the drivers side
1Z87L8S433582

Carb -
17058206

The intake is cast iron

It is a single snorkel

engine numbers will take more time gotta clean off the grease and locate them

 

L in the 5th location is for L48 engine.

very good example but where is your silver on the trim around the windshield and back glass?

 

I gotta go look at mine!!....thanks

 

I believe he means "Targetmaster." That's what GM called their tame replacement crate engines which nowadays bear the "Goodwrench" name.

 

Almost definitely is NOT an L-82:

1. Dual Snorkel cold air intake
2. Aluminum finned valve covers..not painted
3. Aluminum L-82 intake...not painted
4. L-82 hood emblems should be about 6 inches further down the hood
5. "L-82" on the tach
6. 5,600 RPM (AC cars)/6,000 RPM redline (non AC cars) for the L-82. 5,200 RPM redline on taco for the L-48.
7. *Defining fact...5th digit of the VIN MUST be a "4" for the L-82* to be installed from the factory.
8. L-82 has forged 8.9:1 pistons (Cast for the L-48), forged connecting rods (Cast L-48), forged crank (cast for the L48)
9. 2.5 inch Y pipe exhaust for the L-82 versus 2 1/4 inch Y pipe for the L-48
10. 882 big valve heads with 2.02/1.60 valves versus smaller valves on the L-48
11.L-82 cam has .450/.460 lift, 114 LSA/222 duration versus much less lift/duration on the L-48 cam (passenger car cam)
12. L-82 engine is pretty much the same motor as the 330 Gross HP LT-1 motor (1971 9:1 compression).
13 4 bolt mains L-82 versus 2 bolt mains for the L-48.

There are big differences between the L-82 and the L-48...both can make good power when modded but the L-82 is MUCH stronger and easier to make more power. The L-82 can make 40-50 HP with just headers and exhaust. The L-48 will require exhaust, heads and cam to make the same power gains.

Any Gen 1 V8 can make 400 Gross HP with fairly basic mods.
