About 16 or 17 across all nameplates and body styles that color.

You have one of the top color combos for a 71 GT-37
But its your choice

Thanks so much! VERY helpful site! You mean Black w/ Gold stripe is one of the top combos?

Yes
Black & Gold would probably be in everyone's top 3

Okay, good to know... Looks like I should stick with black! Thanks

I have pulled the pan and rod and main caps off my "new" engine... I am going to replace the oil pump and screen... Any recommendations on the oil pump? I see there are 60# rated and 80# rated pumps. Which would give me the best oil pressure on this Pontiac motor? This is a stock 2bbl 350 .

Would a Melling pump be the best?

Also, it appears the rope rear seal has been working well. Unfortunately it looks like I will have to have the rod journals turned. So crank will have to come out.

Okay--Thanks so much for the charts and the info! yes, the partial VIN matches the 160219 on my dash VIN plate.

WN I guess is one of multiple suffix used on various A body 71 250 HP w/4spd designated blocks. ... I see it in the chart listed for a 71 250 HP 350 w/4 speed and mine's a 3 speed but maybe in 71 they didn't differentiate between 3sp and 4 spd with regard to the suffix.

Thank you guys for your time and patience helping me figure out what I've got in these 2 engines. I really appreciate it!

Well, I bought a 76 557 block 400! Seems very solid. So extra motivation to get the rest of the car ready for the engine and hopefully fire it up by spring...maybe before.

Now I need to figure out what to do with the two 350's I have... The original and the one I bought last spring.

You might want to use a pair of the 350 heads on the 400 engine , for better compression ratio / power.
Unless the new 400 is already sitting on go.
It will probably just barely be around 8:1 comp ratio as-is.

Congrats on finding a suitable replacement engine

Thanks! Engine ID is...1976 A or B Body 2 bbl carb 170 HP Heads= 6X Block# = 500557 Code# = X4
So, a low performance 400, which is okay... It runs good and I don't want to put more money into the #94 heads so I will leave building it up more to the next owner... On video, engine sounded real healthy but not lopey... so I assume it's pretty much stock. It had a serious rebuild several years ago and does have an Edelbrock intake though. I don't know if any enhancements were made to the 6X heads or the cam. I know cam, lifters and cam bearings were new with rebuild... So we'll see come spring...

Yes, mine was factory crank, two piece, and likely un-prepared as hell...
