Building my first Chevy Engine
Hi guys,
Newbie to the board and newbie to Chevy engines. My experience, to date, has been building Ford FE engines. Go ahead and take your shots and get it out of your system. :)
I just picked up an 87-90 Gen I 5.7L and am having trouble finding specs on the heads and intake. I was hoping someone might happen to know a couple things:
1) Specs on heads part # 10147898 (combustion chamber and valve size)
2) Specs on intake part # 14014434
3) Recommendation for a good reference book on Chevy part numbers.
Relatively mild build going into a '94 Jeep Wrangler. Just seeing if these parts are worth cleaning up and using or sharing them with the Salvage yard and starting over.
Thanks for your help. I'm fairly confident this won't be my last question here.
All the best,
Mike
Thanks for everyone's help
Guys,
Thanks for all your efforts. Sorry for the delay in responding. Been out of the country on business. Dropped the engine, Heads, Rods, Crank, etc... at the machine shop. These guys are supposed to be the Chevy guys in Cincinnati. We'll see soon enough I guess.
Again, thanks for all your help and I'll keep everyone posted on the build and what I find out about the heads. All the best.
Mike
A quick update on the build and couple questions
Just wanted to let everyone know how my first Chevy build is going. Block, heads, crank, etc... were all clean. Machine shop cleaned them up, milled the heads .006 and polished the crank. Specs are as follows:
Stock Bore
Valve job, new springs, etc... 1.72" Intake, 1.50" Exhaust 76 CC Chambers
Cam-Hyd, flat tappet, Intake .420, Exhaust .443. Duration 270, 280 I/E
Compression Ratio (If my math is correct) 9.013
Performer RPM Manifold
Holley Projection 700 CFM
I do have a couple of stupid questions. Using an electric oil pressure gauge. Where in the sam hill is the sensor bung. Using a new oil filter adapter with no bypass and for the life of me, can't figure out where this thing goes. 1988 Gen 1 block.
Again, thanks to everyone for thei help so far. I'm sure I'll need a lot more assistance as this thing goes along.

oil pressure sending port
Hi Mike - check to see if there is a small port just underneath the Distributer on the drivers side - it's about 1-2" from the dist. housing - I'm building a chevy 350/330 crate motor and am told that thats where the oil pressure sending unit is supposed to go. Beware of the threads in the port- some blocks come w/a/fine thread and some with course. Hope this helps - Bill
