I have the 1967, 327 out of our Chevelle (big block swap) and I was thinking of rebuilding it to put into my 1982 Jeep Scrambler with a th350 behind it. I'm running 31" tires on the jeep. What kind of combo would you guys suggest for this engine? Thanks.

10-1 compression, xe268h cam or equivalent, vortec heads (will they work on a 327 :confused: ).

Yes, good combination if you finish the head conversion with a Vortec intake and needed valve covers and guided rocker arms.

Then make sure they will support the lift you want. And a cheap set of Z-, (-142), springs will top them off, imho..

And the 268 cam should be a dandy at 10 to 1 CR.!!

This is a Jeep so i think low speed torque would be #1. Especially if its going to be a trail rig. I'd take the cam down a notch to something w/ 204 deg dur or less at .050 and shoot for 9:1 compression. Don't know what kind of heads you have but a cheap set of cast pistons is already .040 in the hole and will drop compression at least 1/2 a point. Built a 327 a long time ago with cast pistions low hp heads w/ 1.72 valves and a Crower Baja Beast cam 204/208 @ .050. Had about 8.5:1 compression and ran fine on regular even with a terrible quench height.

I'm with wheels... for a truck, keep the cam small. FWIW, my current 327 is ~8.75:1 w/ an old General kinetics 254/264, 200/210 @ 0.050 cam. Very similar to what Wheels68 describes. Would work great in a Jeep.

I'd say, 9.5:1 CR, Vortec heads, and a 260HE cam would just the thing for trail use. JMO, but 268XE is too big for a 327 with a stock Tq converter TH350 w/ tall tires (assuming the gears are not deep).

I'd recommend turning down a 350 crank to fit the block or getting a small jopurnal stroker crank. That will help your torque a lot.

I was planning on useing the stock Camel Hump heads. This thing will only have to get up to 60 MPH. So I think torque is more the goal here. I'll need to buy a torque converter anyway since the stock one is history.

I was going for the highway is all..

Sorry 'bout that..

You need to get the compression down with the camel hump heads to run an RV style cam. If it is going to be a trail rig you want it to idle smooth and low so you're probably going to be happiest with a short duration cam as long as compression is less than 9:1. A lot of guys I know with trail rigs run MPG type cams with less than 200 deg .050 so they can idle over rocks, etc. Mostly rock crawling in my area, if you get into mud or sand you may want some more duration. May want to look at some heads with more cc or a piston that can lower compression. Most camel humps have about 60-62 cc after they've been surfaced and that will be a little too much with flat tops and a small cam. Since your not worried about RPM a set of low hp heads with 1.72" valves and a 68cc chamber would work pretty well and should be cheap - maybe even free.
