Well, I've apparently got way to much into my motor to be as slow as it is, but here's my entire combo that has gone 12.39 @ 110.


1967 Plymouth Satellite, Full interior, 3770 lbs with me in it.
400 block, .040 over
Forged 413 RB crank, (452 cubes)
Scat H-beam Rods
KB Icon forged pistons - 10.25:1
Mahle plasma-moly rings
(bobweight: 2314)
MP windage tray
OTB Stealth heads with 10* locks & retainers, & Engle double valve springs (350 lb. open)
Engle KV-3 solid flat tappet cam: square 252* @.050; .573 lift; 109* cl, installed straight up.
Performer RPM intake
Holley 830 cfm DP jetted 78f 84r
MSD Digital 6+ ignition w/ Mallory Mag-breakerless distributor - 36* total in at 3k.
Hooker Comp 1-7/8" headers to 3" dumps, down to 2-1/4" full exhaust with Flowmaster 40's
ACC 10" 3500 rpm converter
727 with Transgo Stage 2 kit
8-3/4" w/ 3.91:1 gears; sure grip.
Stock suspension with SSM lift bars, and Summit adjustable shocks
CE bolt in Frame connectors, welded in.
Hand-me-down 28x9x14 slicks mounted on 14x6 rims.

I've made 10 passes and haven't really done anything except mess with the jetting a little. I love the car, and am proud of the motor I built for right at 5-grand total. I am plenty confident that there's more in it, But I'm frustrated with what I see here..... i.e.: a lot of guys going WAY faster than me, with way less motor. I think that a set of better tires on the right rims will help a little, as its pretty skatey on the current slicks.

I think my combo SHOULD be somewhere near the 11.70's. I figure I'll have to make about 114mph to get there though.

Here's what it looks like under the hood. (pretty stealth)

And in the pits at Pacific, with my Dad.

Father--

3800 pound 1969 Roadrunner
3.23 gears
J convertor
three inch system
440 10:3.1
906's with big valves and a little work
.509 MP Hyd
Eddy RPM w/ Eddy 800

Shifting below 5800

12.50's @ 107-108

Running 12's with a big block, especially a 440 doesn't take too much work.

My very first 440 car was a 1968 Coronet R/T. I took the stock 440, rebuilt it and only added a MP 484 lift cam, aftermarket intake, holley carb, and headers. With the stock 3.23 gears, I was running 13.3-13.4 & 103-104 mph in a full weight car.

Wanting to get into the 12s, I had the heads bowl blended (mild port job) and added 2.14 / 1.81 valves and changed the camshaft to something a tad bigger, I think it was the MP .509 lift cam. Same intake, carb, and exhaust. I did add 3.91 gears. Next run out, 12.49 @ 108 mph.

Finally, I dropped on some Edelbrock Heads, a Solid Tappet cam from Hughes and crane roller rockers. I also removed the stock steel hood, and added a year one fiberglass six pack hood to save some weight and look aggressive. I moved the battery to the trunk as well. I ran a 11.9 @ 114.5 mph the next time out. 60 ft times were 1.75.

My old 383 Dart. This was my Dart before my son bought it and I had a mild 383 in it. It was a stock 1970 shortblock that I cut the 452 heads and decked the block to get a true 9.5 comp. It was stock pistons in the stock bore. I used the MP .484 cam and stock valvetrain including stock rockers. Had Comp single springs on the 452 heads and we did some mild pocket porting on the heads. I had the Performer RPM intake and a 750 DP. CPPA 2" headers and we used a stock dist I recurved. It had a Turbo Action 10" tight 3000 converter and a RMVB. Had an 8-3/4 with 3.91's and used McCreary G/60-15's which hooked good on that car. It weighed just over 3500 with me in it and ran a best of 12.31 @ 110. I was very pleased how well that car ran with that so mild 383. It now belongs to my son and has a .030 over 400 (406) in it and has run 11.40's. Ya cant tell me 383's dont run good. Ron

Here it is now with the 400 in it. And it is a great race with me and my 63 as both have run 11.40's. Ron

My old '64 Fury:
440 .040 over, stock crank, 440source rods (I didn't have any good LY's at the time), true 10.03:1 compression, .509 cam in at 4* advanced, home ported 346 heads that I did when i was 16 using the MP templates and blending the bowl into the runner... eddy rpm and holley 850 dp, stock electronic ignition with orange box, 1 3/4 hedman's with homemade 3" exhaust with flowmaster-type mufflers ending before the axle.. 4200 flash 9.5" ptc, 3.91's and 275 drag radials. 3525lb with driver....11.74@114 through the mufflers on pump gas.
