Post your 500ci street/strip combo's with ET

[68 HEMI GTS]

Let’s open it up to flat top or dished piston engines only. No domes (unless it’s a Hemi). No Dyno queens. Just street strip motors (that actually get driven). 500 cube range +/- 30 cubes. Proved as much detail as possible as well as any ET differences you've seen with parts swaps such as cam shafts. These combos seem to be very popular and lots of people looking for info so be specific.

All runs were driving to the track and running air cleaner, mufflers, and no tail pipes.


Six pack with 500 cfm center

Ported TM6 with 1050AN proform carb
1" spacer

Head flow sheet

Broke the TCI converter. Went to a tighter PTC, flashes around 4400. Slowed the car down slightly.

I did make 1 pass with a turbo action J Converter back in the spring. The car left super violent and actually felt weird so I peddled it once. Still went 10.95 but look at the 60! The vert was very fast but I didn't like it for driving around. I only got 1 pass that day due to rain. I'm pretty confident I would have seen some .80's had I made more passes.

Rules are simple, no high compression race engines. No Dyno queens. Just drivable street strip motors in the 500 cube range +/- 30 cubes. Proved as much detail as possible as well as any ET differences you've seen with parts swaps such as cam shafts. These combos seem to be very popular and lots of people looking for info so be specific.

This thread needs/deserves a lot more attention, it has sticky potential if everyone running strokers chime in. There’s always people asking about stroker combos. I’ll list mine below.

 

[1967coronet440]

I don’t have any dyno or track numbers to report but maybe you guys can take some guesses on HP and ET in a 67 coronet let’s say 3600lbs.


440 stroked and poked to 505”
12:1cr
Eagle crank and rods
Mahle power pak flat tops with 8.0cc valve reliefs
Comp cam .693/.694 263/[email protected]
T&D 1.6 ratio roller rockers with oiling upgrades
Edelbrock Victor max wedge heads OOTB porting,
Ferrea valves.
2” TTI headers
Fitech 1200 fuel injection
Edelbrock super victor intake
BAM Roller lifters
Milodon 7qt pan
Milodon pickup
Felpro .039 Head gaskets

Trans is from A&A, their super competition trans with a brake and all the goodies 5000 converter

Rearend is a strange s60 with S trac differential and 4.10 gears and 35 spline axles

That's one super fine Coronet you have ! And that combo sounds like it should hit 9's when its tuned in. Good luck with it. Ron

Thanks Ron, I would be very happy with a 9 second pass

Should fly, I bet it runs 10teens/twenty’s pretty easy! May have to work a little to widdle it down from there.

I would be ok with hose numbers for a first season lol

 

[69 GTX]

Is 12:1 a flat top piston?

 

[1967coronet440]

Is 12:1 a flat top piston?

They’re mahle power paks with 2 valve reliefs, I think cr may actually calculate to 11:9.
