87 350 TBI motor swap with built L-48 350
Hello all
Well I bought a 83 blazer that has a 87 TBI motor in it with the 700r4 and its getting tired.
I have a brand new built 1970 L-48 350 with all the goodies on it and would like to swap it in if its possible.
My question is will there be any issues using the TBI? can I just yank this motor out and drop in the old built L-48 and then bolt the TBI onto the intake and call it good?
Thanks in advance for your help.

Why would you put a restrictive stock TBI setup on a built motor? Stock TBI relies on a known set of engine operating parameters. You need a specific camshaft, need the TBI distributor, all the sensors and the ECM.
Just buy an Edelbrock dual plane manifold, 600-ish cfm carb a set of headers and a MSD HEI dizzy. Power wire for the Dizzy, separate power for the choke, fuel for the carb and vroom-vroom...

The 350 I have is bored 40 over, weiand stealth manifold, tube headers, thunder cam, roller rockers, solid lifters, peat Jackson gear drive, ported head and have a flame thrower HEI. All brand new and has been sitting in my shop for 3 years now.
So think I should toss this motor in and convert back over to a carb?

So get a four barrel intake that will accept a square bore carb and get something like the Edelbrock E-Street fuel injection setup. They make great power, are extremely efficient, and are easily retuned should you change heads or cam down the road.

the tbi unit flows 450 cfm,its not too bad,but its still a little small for a decent 350. You could slap it together,but you are going to run lean,and its going to need a tune. after all said and done it'll be easier and more efficient to run carb.

It depends on how much $ could spend.If you can afford it there are some fuel injection systems that can run on your set up.If your on a budget then I would recogmend what Mossy said or convert it back to carb.Another alternitive if you can get all the componets neccasary and have the $ for them would be to run tpi.

If I did go carb should I use the fuel pump in it and a regulator/block off plate or run just turn the pump off and run the maniacal pump?

Since this motor is not stock it may be better to go with a carb uh? Sorry for being such a newbie.
