I found an old magazine article online featuring another 302 build, thought this made for an interesting comparison.

Just for another quick comparison, my '69 302 engine rebuild was completed and dynoed last week and the results were almost identical to the "stock rebuild" version of the article you just posted.

I basically utilized OEM engine specs throughout, other than headers with 1 5/8" primaries and 3" collectors.

My engine is a screamer but yours would run circles around it! Excellent project!

Music to my ears! [img]<<GRAEMLIN_URL>>/worship.gif[/img]

Thank you Eric for the hard work and time that you spent on the 302! [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

I'm soo tired of people that don't know enough about the 302 to have an opinion on how

the engine was such a disappointment because it was only offered for three years...has

no torque or low end power! [img]<<GRAEMLIN_URL>>/bs.gif[/img] If you build it right, with the right combination of

parts that WORK together and good Valve train...the 302 will be an outstanding engine.

The more you feed it...the more it wants. The Cross Ram sure does add more ZING!

I read everything you did Eric and am very impressed on the results and the Dyno.

I don't think John Duzac or Jerry MacNeish have a problem with how a 302 performs!

If anyone has a spare crossram system laying around that they're not doing anything with, I'd be more than happy to test it the next go-around. [img]<<GRAEMLIN_URL>>/grin.gif[/img]

In case anyone's interested, I just dug out the flow sheets on the heads:

Lift----Int--------Exh
.200---128.2-----111.5
.300---179.2-----142.6
.400---213.6-----161.9
.500---223.4-----172.9
.600---225.4-----180.1
.700---229.6-----185.2
.800---231.8-----186.9

That puts it roughly at 2.19 HP/cfm. Dave says there's still plenty left, should be able to squeeze another 20-30 cfm w/o having to resort to exotic mods and w/o killing air speed.

I hope to have the engine ready for another round of testing by the end of the year.

Eric,

Are you willing to predict what kind of vacuum number you may pull after the change in the camshaft? This is rather inspiring for a Rochester F.I. build for my 62 Corvette. Vacuum is everything to mechanical F.I.
