Happened a month ago, been away from the computer.
But anyways we started from a dig both times, first race I had him by a car length from the start because he got a bad launch but our cars were running dead even as in he wasn't gaining on me and I wasn't pulling away.
Second race I didn't get the greatest launch so my front fender was next to his door, but I'm pretty sure when he was nearing the top of second I was inching up on him (I could hear his car over mine) but he missed third and I got that one too.
His car is stock
My car: '70 Polara, factory rebuilt 440 magnum .030 overbore, back cut intake valves (only machine work done), six-pack pistons, ram-air, 750 Holley, factory reman 1500 stall converter, 2.5 inch dual exhaust, 383 exhaust manifolds, cast-iron stock intake, 2.76s out back.
I would like to say that I also obtained a 3.23 open carrier that I'm swapping in this weekend, I also want to get rid of those tiny 383 manifolds for at least 440 log manifolds, but most likely HP manifolds in the future.

What do you guys think?
The 383/440 manifolds are identical (same part numbers) You need the HP versions, not the logs. HP's flow 30% more, but still can't compare to headers
Pass side HP manifold would work from B/E/C body however the drivers side is C body specific.Money would be better spent on Hedman shorty headers but if you need a drivers side C body HP manifold I have one collecting dust.
I have run HP manifolds,Hedman shorty,Hooker Super comp,and TTi on my 70 Polara.The shorty header is the best bang for the buck on a mild motor.Hooker and TTi are $$$.
An Edelbrock performer is an upgrade over stock.The rpm won't fit under my Polara hood.I have run a Holley street dominator but I know run an old Edelbrock CH4B as it idles so much nicer with a dual plane intake in my setup.

Good show, Poaradude! But that's the sad state of affairs for our big heavy cars vs modern middle-of-the-road performance cars, unfortunately.
'Plain' 383s and typical C-body gearing are probably outgunned by lots of 'boring' cars out there, and even a mild 440 will have its hands full. We no longer have the edge we had on cars from the late 70s thru the early 90s. In the 80s-90s EFI and OD/gearing leveled the playing field, but nowadays so many cars have so many gadgets (VVT,, variable intake manifolds, distributorless ign, 6-8-speed transmissions) that they now have the edge. I'm not sure there's even a playing field anymore.
And I'm not even thinking of performance-slanted cars like Mustang, Camaro, Chrysler SRT8s, various GM cars with LS engines, Subaru Imprezas, etc. I'm talking about 274hp Kia Optimas, turbo'd Buicks, 260-ish hp Accords and Camrys. Cars people are buying without realizing they're getting a potent performer.
The last 3 rental cars I've had (Chrysler 200, Camry, VW Passat) were all vanilla 4cyls with 6+ speeds in the AT, and each of them buzzed up to speed VERY quickly.
The only edge I think we still hold is a 60-90+ mph run on the highway, where our ability to easily gain speed in 3rd can shine (against the vanilla cars, that is).
