alright so i need help i recently pick up a 87 tran am for 1500 and it has a 350 4 bolt main mystery engine in it and getting parts for this engine has been unbeleavable beacuse i have no clue what year the engine is and what it came out of and right now my problem is i need a oil pan with the dipstick on the left side of the block so far by looking at it i be able to find out its a 4 bolt main probly from a truck the origonal block paint was green so if anyone can help me by identfying this engine or even telling me what pan i need please help me out by leaveing me a comment

 

GM never painted any SBCs green, and John Deere never used SBCs. The oil pan you need should be for any '75-'78 Camaro. If you want better info, clean the grunge off the block and get us the numbers. The casting number is at the left rear, the stamped info is at the right front.

 

alright ya that was stupid now that i think about it i just wasnt sure if pontiac made a green block but its red right now and you can see on a few hard to get spots thats its green so i have no idea but heres the numbers
3970010
L87 i thinks these are the numbers you need

 

I looked up the Casting number and it is a 1969-1979 block.

All you really need to know is that it is a 350, pre-87 so it is a 2pc RMS. What heads are on it, pull the valve cover and look for their casting #'s as well.

 

My books are showing that casting # to be a 2 bolt main block.

 

That block was used in both 2-bolt and 4-bolt configurations. About as common as dirt.

 

so i got the oil pan it was a 1970 block 350 fourbolt main still no clue what it came out of but whatever runs great so i gunna stick with this block seems like it would mesh good with the car only now is to decide what kind of carb to put on it. its between a holly double shot not sure the model or a edelbrock not sure the model i think the edelbrock beause i have the edelbrock torque intake any tip would be greatly appreciated

 

As in Torker intake? Hopefully not a Torker II.

Neither one is a very good street intake. Better to sell it and get something more street-friendly like a Performer.

Edelbrock makes good intake manifolds (when properly matched to the rest of the engine). There is absolutely no reason to assume you need to use an Edelbrock carb to "match" the intake.

 

ya i ment torker and its not a toker II why are they bad for the streets if you dont mind me asking and should i go with the holly carb then right now i got a rod qjet 4bbl

 

keep the Q-jet very good carb, get either a performer or a RPM manifold, the single planes are good for straight line acceleration but not so good on the street. Unless you are constantly flooring it everywhere your car will be slower out of the light and feel slugish while just cruising, mileage is out the window as well. A dual plane manifold will always give you better driveability for a street car.

 

The Torker powerband starts at 2500 RPMs, and that's being generous. Flooring it doesn't help, it'll just slug it's way until it gets up to 2500 RPMs. Of course, if your torque converter stalls well above that, it'll get into the powerband quicker, but you'll always be reving it up to get moving if that's the case.

As stated, a Performer with a q-jet would be fine, assuming a mild cam.

 

alright thanks for the help ill stick with the qjet and look in on getting a performer rpm

 

Do you have any idea what cam is in it? While a Performer RPM is better than a Torker, most factory type cams are so mild even the RPM is more than what is needed.

Since you have a T5, a case could be made for going with a double pumper Holley type carb, probably something in the 600 CFM range. Other than that, the q-jet you have is a better choice than any other option.

 

i have no clue what cam is in it im guessing factory tho so what ever the 1970s 350s came with out of factory and were can i find a cowl hood in ontario without haveing to order from the states

 

I'd drop the RPM choice and just go with the performer manifold the stock cams don't like to hit anything above 5000 rpm.
