[EZ Nova]

Sorry, but I'm a little confused trying to follow this thread??

Here's what I THINK (??) I got so far:

1. Do did a GREAT job restoring the Chevelle. It's a BB 496 you did, and stick.

Confusion starts with:

1. It's a 496 that you did a separate "build thread" on. You linked it back a few times. BUT that thread say "Remember, the results up to this point are still with 100% original, UNPORTED cylinder heads with stock 2.19 1.72 valves."

2. In the update thread you go on to say you got 840 casting in 2 weeks and of to Chad for porting as shown in the picture. Page 11

3. See on page 13 that Chad got some nice results out of the 840's.

4. Never got it back to the dyno? 25 pulls on it with stock heads and NOTHING to figure the new heads?????


I missed cam timing so cant say what I figure the heads help was, say 70hp?? So a 670 hp motor and only getting 12.0's or high 11 with a Mt 275 Dr tire (which by the way probably has the most advances as any tire today for racing)??? I thought hat car should have been over a second faster. My '69 Nova set-up like this (M21, 4.56, 9" slick) but with a lil mild 396 went 10.47. Basically a STOCK balance L-78 STANDARD bore 402 with only ARP rod bolts. Stock pan, PORTED 840's, but did have a strip dom intake and reworked holley 800. UT I did have a solid roller .660 cam.

Seems like you know what your doing, and been around these cars for a while, but what are we missing???
