What should I do about my '72 350
I spoke to a shop about reviving my '72 350. They said they would do a remanufactured longblock job for $850. Below is what that entails:
Bore and hone the cylinders Grind & polish the crankshaft High-performance 3 angle valve job Resurface heads New parts: Rod, main, cam bearing Camshaft Front & rear main seal Oil pump & lifters Timing component set Freeze plugs Valve seals Complete gasket set I wanted to get some input from you guys/gals; do you think this is worth it? What have been your experiences with doing a rebuild on an old block? Thanks. Here is a picture of what the engine looks like right now. |

I also have a 350 and one cyl is bad. I went to a local shop to see what they could do and their price was 1200. They said they warranty the work for 6 months or 5000 miles. Which ever comes first. SO I have been looking at rebuilt Chevy motors which is warranted for 3 years or 36,000 miles. Those are 1300 dollars. I have to save up a bit but thats what I am looking at.
Thanks. Truck69. |

If I were goin' to redo my 350 in my 4x4 I'd put in a 400 crank & have it stroked to 383 for better low end torque as well as an aftermarket cam for better torque & mileage. It'd be a bit more expensive, but well worth the effort. My main beef w/ the factory engines has always been the terrible mileage & lack of low end torque.
Before they do any machine work I'd have the block checked for flaws or thin cylinder walls so you don't waste money on machining a bad block, crank or rods, unless they'll guarantee them w/o the check. It can really save you a lot of headaches.

I scanned your new parts list and didn't see new pistons on there.
I'm hoping the $850 includes new pistons (you need them if you bore the cylinders). Right out of high school (late 80s) I bought a used 350 on a stand for $50. When I checked the holes they were still in spec. So I just honed them out, put in new rings, and still run that engine today. Talk about a cheap rebuild. Oh yeah. I had a shop go over the rods and I installed new bearings (of course). If you need pistons, consider a 383. For the price of what you need to buy anyways, plus a crank, harmonic balancer, and flex plate, you have more torque and hp.
