Question

I' m having a '67 327 rebuilt for my '68 camaro It will be .030 over with a edelbrock 600CFM carb, performer rpm intake, vortech heads with 2.02/ 1.60 valves and maybe a XE256 crane cam. The pistons will probably be cast with a decent set of rings. the bottom end will remain stock but just freshened. I believe the motor was the 210 std output. It came from a '67 chevy truck. Any guesses for HP and torque? I would love to be in the 300- 325 range. Any thoughts, suggestions

thanks

I'd say you should be right at the 300 HP mark if you use a flat top piston and a cam with about 215* duration.

Looks like a nice street 327 combo to me.

PS. That 300 HP guess is WITH a good set of headers, free flowing dual exhaust system, and tuned well. With manifolds you'd be closer to 270-280 HP.

I am building the exact same motor only a 350 with dished pistons and a performer with a Q-jet. I will let you know how it works in my 67 Nova wagon with a 3.42 low ST-10 and 3.08s.

Thanks guys. I talked to my engine guy over the weekend. We discussed being at about 10:1 compression max which I think it will still be streetable. I'm definitley going with headers and some flowmasters for this set up. I was thinking about a 600CFM carb? Right size? What do you think.

thanks

Hey Rusty,


I'm going to go with almost the exact same combo on my 327. The only difference is that I will stay with the stock 1.94" valves on my Vortec heads and will probably go with the Crane 266 (210/216 @ .050 .445/.450 lift) on the cam. The Crane 266 has about 2 degrees less duration on intake/exhaust than the Comp. XE256.

So the 300hp estimate is about right on from all the thrashing I've done on this board. If you get yours together before mine, I'd love to hear how she runs. BTW, I was planning on a using a 600 Edelbrock or 625 cfm Carter carb. on my combo also. I don't think that these combos need any more carb than that.


Good luck,
Mark P.
