After my one journey to the strip this year, there is no improvement over last
year and I'm still 0.20 seconds from cracking into the 11s with my near 3800#
1965 Belvedere. How do I pick up that two tenths or so without a spending a
fortune. Keep it under $2,000 (or a lot less).
My first thought is reduce weight. Scrape off the undercoating and take out the
jack and spare. But I don't want to get carried away with weight reduction as I
want the car to look "stock".
I'm pondering a serious day at a chassis dyno with someone who knows carbs -
that might cost me $500 or so.
Other more expensive options is changing the pistons to get a quench motor with
the existing open chamber 452 heads (is that even possible?). $300 for KB
Hypertech step pistons. Plus rings, gaskets, etc.and a engine rebalance.
Next step is to go to Performer RPM heads. I'm concerned about power loss as I
already have a Stage 1 port job by Koffels on the 452. One restriction is I want
to run pump gas - 93 octane. Bare heads in the $1,200 a pair range plus maybe a
$100 to install the valves out of the 452 heads.
I'm already running a near 550 lift Comp Cam and think that will not change.
60 foots are in the 1.73-1.74 and it looks a little sluggish off the line. (see
"Don Gallimore at Pinks All Out" on YouTube) The rear's a 4.10. Maybe a 4.56
with the existing 4100rpm flash stall converter might do the trick. The 9" tires
are not stressed now so I think they can handle the additional torque
multiplication. It's a Dana 60 so it's not a low cost changeover. Could fixed
one of my 8 3/4 units - destroyed a good number of them in my 4 speed days - so
I've got a lot of parts. That'll cut another 50# off, too. Can it take the load?
That'll cost me less that $500.
Anyone care to offer some suggestions? Thanks in advance.
