Mine is not the fastest out there, but it is a nice street friendly combo that has been running for thousands of miles and never overheats.
340 .30 over, stock stroke with original forged crank. Stock rods, forged factory style replacement TRW pistons with 10.1 compression. Comp XE274 hydraulic cam, unported X heads, Edelbrock Air Gap intake, 650 Holley DP. 3.91 gears, PTC 3,500 converter, 28" tall drag radials. Car weighs 3,500 pounds with me in it.
Est. 400 HP at the flywheel based on quarter mile time of 12.91 @ 103.7. No nitrous, aluminum heads, or stroker needed. Still need to play with the timing too. Driven to and from the track, runs consistent within a couple thousandth so it makes a good bracket car to boot.

Not sure what mine makes, probably about 350-375hp, but its a VERY simple engine combo.
'77 360 with stock pistons Magnum Heads with R/T Springs & Retainers Summit K6901 camshaft (218/228 with .441/.441 lift (.470/.470 with the 1.6 rockers) 1 5/8" headers Edelbrock Air Gap intake (Magnum type) 600 Holley.
This thing runs strong!!

360 block, 408 stroker. forged Ross pistons (10.2:1), Eagle cast crank, H beam rods, .600 lift, scorpion rockers, Isky springs (can't remember rate), Scott Brown custom ground hydraulic cam (248/254@.50) Ported Eddy heads flow 284 cfm (gasket matched), stock M1 intake, Proform carb... flows like an 850. TTI headers. 480 horsepower, 500 ft. lbs. tq. With a 3.91 rear and a 4 speed, it's all you need on street tires... I spin through 3rd gear. If I were building from scratch, I'd only change the carb and MAYBE up the compression to 10.5-10.7 or so. Buy a Demon. My money is far better spent on tires at this point though if I were looking for the best e.t. and since I don't race, I don't need slicks or drag radials, so basically I am where I need to be: HAPPY!

Ok here is my combo:
+0.035 over 340 4" Eagle forged crank reconditioned stock rods custom forged Venolia pistons 9.5:1 compression stock 340 'X' heads completely gone thru (no porting) Mopar Performance 484 Purple Cam (241/241, .484/.484 lift 108 lsa) new stock stamped rockers Edelbrock RPM airgap mainfold (dual plane) Holley 770 Street Avenger carb (it has been re-jetted) FBO ignition system TTI headers and TTI 3" exhaust system with Flowmaster 40 mufflers 3.91 gears 4-speed 70 Cuda
The car dyno'd at 375 peak RWHP when the clutch started to slip at 5000rpm (so there is still more HP in there) and 484 peak RWTQ. Figuring a 10% loss for the drive train this puts the HP at about 420 at the crank (when the clutch started to slip) and 537 TQ at the crank.
Future plans for the motor:
-Ported Eddy heads -10.5:1 (or higher) compression -Roller hydralic cam and rockers (the cam will have a little bit more duration and more lift then the current cam) -850 Holley DP Carb
With these upgrades I hope to make around 500HP/500TQ at the crank. Looking at what other people have posted with their combos this should be possible.
70 Cuda 340 4 speed - now stroked to 416ci (SOLD) 2017 Mustang Shelby GT350

Here's the one I plan to bracket race....Quick77R/T built the shortblock 360+.030 roller block 11:1 Eddie closed chamber Heads...bowl blend, Good VJ and open the pushrod pinch to .980 (per RyanJ's recommendation) Hydraulic Roller 236/240@.050 ..554/.540 lift 112 centers, 107ICL 1.6I 1.5E rockers Performer RPM...minor porting 830 annular Holley 1 3/4 headers 904 Lock-up w/Shift kit 3200 stall 10" converter * 3/4" b body rear, 4.10 gear 28" x 10.5" slick Should be similar to a few others here like Ademon's. A basic, reliable, powerful, nice combo. Looking to go consistent 7.50's in the 1/8th in a 1992 Daihatsu Rocky that weighs ~2950 lbs w/me in it. 87" wheelbase so that's why I spread the lobe centers and oversized the carb to kill a off idle and little midrange (shiftpoint) torque to make it more tractible until I get a handle on how to make it go rounds. I may go to a single plane if it still has too much torque off the line or a Vac secondary if it goes a little too quick. I figure it should make ~425 (well probably a good bit more )by ~6000rpm pretty easily.
