We've got a '68 327 engine that has been modified sometime in the past 20 years. All the paperwork that came with the engine is hand written and we're just trying to verify some of the modifications.

So here's the problem:

There's a card with cam measurements on it that we think says 'Sealed Power', but the measurements as follows don't fit anything they offer. Anyone have any information on it or have run a similar cam?

Just trying to size up if what came with the car(carb/pistons/headers) will match well. And also trying to figure out where the power band will be with this cam. From similar setups I've read about, the powerband should be approx. 3500-6000rpm, give or take a few hundred each way?

SAE dur. 287/287; @.050 dur. 230/230; Cam Lift .320/.320; Valve Lift .480/.480; Lobe Ctrs. In.107/Ex.111(w/2deg. Adv, so 109 actually)

@.050 Cam Lift; BTC 8, ABC 42, BBC 46, ATC 4
SAE J604; BTC 34, ABC 73, BBC 72, ATC 35

w/ performance springs given as part no. 212-1183, 2in. length,1.160 height, .192 diameter, 1.700-1.210 compression (@ 104-116 to 282-306)

Found an elgin with similar specs, the E920 from another forum archive (http://www.jalopyjournal.com/forum/a.../t-110384.html)

we're going for a fun but driveable street car that can pull well to 70.

10:1 forged pistons(92+ octane gas), 3.73 moser rear, 24" tire(870 revs/mi), 650cfm holley, hooker headers

Just need a tranny, looking at richmond t-10 from summit but not sure if we want 2.88 first gear or 3.42? leaning toward 2.88 will give us around 35mph in first @ 5500 rpm

Thanks for any help or knowledge anyone can impart.

 

Sounds very close to the factory specs for the old 375HP solid lifter cam that the 327ci Corvettes had. Very nice cam for street-strip use.
