Tell some combos here for your street small blocks. I have a 340 and 360 block. Trying to decide whether to build a stroker engine or spend the money on a basic 340/360 combo with a healthy cam and decent compression. It'll be going into an a body. Thanks

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!!

Last winter I pulled out a .30 over 9 to 1 340 with stock X heads, 292/509 cam and an RPM Air Gap intake with a holly 750 carb and TTI headers. I built a .40 over 418 ci stoker motor with h beam rods and diamond pistons (10.9 to 1 compresion). I also had a set of edelbrock heads ported and I pretty much used the rest of the parts I already had. The motor makes about 525 horse power. It is in a 70 Duster with a 4spd. and a 3.91 gear. The only thing I can tell you is the first time I got into it, after it had a few miles on it of course, I almost had to go home and change. It was worth every penny.

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!

I guess I'll jump in here to.

+.040 360
KB flat tops
Magnum heads (worked on with 2.02 valves)
M1 dual plane
Comp Cams Magnum 280H total lift .512
Crane roller rockers
MSD 6AL and billit dizzy
650 Speed Demon
1 inch spacer
1 5/8" tubes to 3" outlet Dynomax headers
2800 stall tc
727 reverse manual valve body
4:10 8 3/4
SS springs
M/T sportsman pros

This engine combo dynoed 392HP/412 TQ with a Comp Cams 268H and before I installed the roller rockers. I don't know if the spacer and Speed Demon gained me anything or not but the seat of the pants dyno tells me they did. I estimate my Hp to be in the 425 range now.

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.

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.
