In the second half of the 1980’s – officially in 1986, Chevy converted small-blocks to a one-piece rear main seal which makes identifying these engines really easy. Jeff Smith: I’ve built more than my fair share of street-easy small block Chevys and one combination is a favorite. Do you have a recommendation for someplace to start? Thanks I’d like to rebuild the engine by putting rings and bearings in it. I could just buy a Chevy crate engine but I’d like to do the work myself. I will probably put headers on it, so except for a small Holley four-barrel carburetor and intake manifold, that’s about as wild as I want to get. The trans will be a TH-350 with a stock torque converter and whatever the stock gears are in the rear end. That would open up more cam options too, and id bet you could find power up to the 272 range with ~520 or so.įor carb I would stick with a 750 Holley like the 0-80770, its a 770 street avenger with electric choke and vacuum secondarys, and a capable carb for performance while not losing streetability.I want to build a mild, 350ci small-block Chevy for a ’77 Chevy pickup I’ll use as a daily driver. You could order those and have the valves cut and some exhaust work done on the heads at the same time by a machine shop. GMPP makes "performance spring kits" that are relatively cheap. Ive contemplated this as an engine build several times, you can build this using 100% new components for around $2500. It doesn't work any more but I used to have a dyno sheet of a 350 with hyper pistons (5cc), vortec heads, XE268H, Eddy RPM Air Gap, 750 holley SA, 1-5/8ths full length headers, flowmaster super 40's, and a TH350 making 321hp at 5800rpm at the wheels. I cant really speak to the lunati either way. With the amount of support that Comp gives to racers, and the level of quality and technical support, I pretty much only look at them for camshafts. Thoughts on cam selection? I don't believe this block is setup for a roller cam.So, stick with the stock one for now? Hydraulic flat tappet? Lunati? Comp Cams? 262? 268? Thanks. Will my 600cfm Eddy be enough? Or would the 650cfm Edelbrock AVS be a better fit? Would the 800cfm Edelbrock AVS be too big? If I buy a new carb now, it needs to be sufficient for the LS swap as well. I'd like to keep the heads the way they are.I'll be installing the new heads and intake sometime in the next couple of months, and it just needs to hold me over for a year or two when I do a 500+hp LS swap. It is a very stock 350, casting numbers 10054727, '87-'95, center bolt valve covers, non-vortec, summit racing headers, and an Edelbrock 1406 600cfm carb. I just picked up a clean used set of Vortec 906 heads (assembled w/valve springs, self aligning rocker arms) with a Edelbrock Vortec RPM intake and am looking for some suggestions.
Looking for a few opinions on carburetor, camshaft, etc. Hey guys, I posted this over on TC as well, but looking for all the advice I can get.
