Subject: Need a bit more Speed
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.
Akron Don
