Pat. If you pull the intake off you will find the date code on bottom. Looks like it's a later '68-'70 intake.I like the aluminum waterpump. I has a GM one like it. New in the box . Good luck on finding the original carb I hope he still has it. The "new" 3310 is a 750 and the "old" 3310 is 780. The boosters in the 780 are downleg type with round hole and the 750 has straightleg with a bar across hole. At least that was what was available a few years ago. I have a 780 on my chevelle. It was on my previous 454 that dyno tested at 461 hp 537 torque with 9.2:1 compression and 89 oct non alcohol gas and also with an 800 dbl pump and MSD ign. Made 425 hp with the 780 and recurved hei dist. Secondaries popped open at 3600 os so and shook the dyno.lol. On the street it felt like hitting a nitrous button when they opened and it went from 3600 to 5600 very fast. 5600 was the peak. We tried turning it higher but it didn't make any more power beyond that. Calculated on paper it would've been good for 11.70@120. Was fun to drive for the 5 years I had it in there but I never got to run it at the track as it was my daily driver at the time.

Thanks for the input, if I change cams the first one I would look at is the CompCams LS6 Nostalgia Cam (www.compcams.com/Company/CC/cam-specs/Details.aspx). It is hydraulic and has a similar sound to the LS6/L72 cam. And I would carefully wrap up and save the cam and lifters I took out just to have them. But we will see after a couple months trial.

I will not keep the suspense (if there was any) going any longer. I got the motor for $2500. I was looking in my rear view mirror for blue lights all the way home, lol. I figure I can get at least $7-800 for the Corvette stuff on EBay if I am patient, so my net cost is borderline ridiculous.

Way to go Pat, you stole that engine. I bought an L72 for my 68 Biscayne and paid a lot more than you did and I still think I got a pretty good deal.

LS6 454 sounds pretty good at 5600 too.

Yup...for sure. The engine in my Gasser is an LS6 with a 5800 rpm chip in the MSD.

$2500 for a complete L72 is the deal of the year...holy schmoley!

Just heard from the shop I bought the motor from, I asked them to ask the previous owner some questions. The motor was bored .030 when it was rebuilt, and hardened valve seats were installed. He ran it on pump gas with octane booster. So that gives me good info to start with.
