the zl1/L88 is an insane cam, its somthing like 265@.050 lift with a 108 centerline. its good for racing and just a little bit driveable in a 540. but do your self a favour and get a Comp 292 magnum or somthing like it (244@.050)

and for gods sake. put in the big block, if you allready have it... the stock ovalports will outperform even stage 2 bowtie smallblock heads

besides you allready have the engine, so whats the prob, and save the sb for your wifes car :-)

Cool

I don't have ANY BBc's any more. The sbc build up is much cheaper and the engines lighter and gas pump friendlyer. A BBc will use $5 worth of gas to the grocery store and $5 back home. I guess it depends on How Deep Your Pockets are. Build up the Front suspension BEFORE dropping in that BBc if you do run it. Gotta Love This Hobby!

WHY DID YOU CALL IT THE TROUBLESOME 427?

If you are building a smallblock or a big block, and using aftermarket parts on both, (forged rods, crank, pistons...) the big block will cost more, but it will be worth the money if you build it right. What I mean by build it right, is to take advantage of the displacement capeability of a big block. If it comes down to a 396 big block or a 406 small block, I would have to go with the 406. But, for what it would cost to build a all forged 396, you could build a 496 with a stroked 454 block. Personally, unless you are on a really tight budget, and are going to have to use all stock parts, I would not build anything but a 496. As far as stock parts go, you can make way more hp out of a 454-468 than a 396 for the same money. I have a friend that just built a 468 with cleaned up set of stock oval 049 heads with the 2.19 1.88 valves, a 240 @ .050 duration hydraulic flat tappet cam, and 9.5:1 compression. That motor made 560 hp and 560 torque on a dyno, not an estimated number.It would take some high dollar aftermarket parts, along with a solid roller cam, and way more RPM to get that hp out of a 406 with 9.5:1 compression.

I agree with Poncho..... the SBC and the BBC are bothe great platforms. Personally, I'd hit it withe the 396. Everybody and their dog has a 350 or 400 or even a 406, but a 396 BBC is a little rarer, and a bit different. They can make great power/torque with moderate investment, and there just aren't that many around. Go ahead, be different, and enjoy the car!!!

Hey Firestone, what were the complete specs on that cam you were talking about that your friend used on his BB? I have a BB with similar specs and I'm looking into different cams right now. Just curious.

If you got the 396 already, build it. Darn good engines! Hg

I'm waiting for the answer on that one myself.

If you already have the 396, use it. Unless you have a certain goal in mind there is no reason not to.

I was off on a couple of specs, but over all I was pretty close. Here are the specs on that 468

781 heads some bowl work flow 290 on intake 2.19 1.88 valves
9.5:1 tested compression
comp hyd roller 242 248 @.050 and just under .600 lift it was a custom grind and he didnt remember the other specs
victor jr intake port matched W/ 850 demon

This motor made 566 hp @ 6100 RPM 560 tq on pump gas
If you are looking for a cam like this, I would recommend the comp XR294HR(242 248 @.050 .540 .562 lift 110 lsa 2800-6100 RPM) With a set of high ratio rockers, this would be very close to his cam.

Big Blocks

I have read "if built properly, a sb blah blah blah". A half way bult BB will still out run a sb any day.

Keep the BB!

If not, I will take it off your hands.....
