385 stroker

Hi everybody, i had the machine shop build my sbc stroker, i would just like to know what do all of you think it makes for hp and torque, and if the combo sounds ok. Ok its a 350 stroked to 385ci . It has a eagle crank and rod kit, with speed pro flat top piston's , the heads are pro topline steel , with 64cc combustion chambers, with 200 cc intake runners, i have a comp extreme energy cam (xe294h)with 519-523 lift. With speed pro piston's , a weiand team g intake, a 1" phenolic open spacer, a holley 650 dp, a unilte distributor with no vacuum on it. Comp 1.5 full roller rockers, and a 7 quart oil pan. I had a guy time it for me, and it felt good, then i had another guy, that drag races check the timing a few weeks later, and he said the timing was at 48 degrees, he said thats way to much, so he said he was gonna set it down to 34 where it should be. The next day i noticed, the car had less power, when i would shut it of it would want to run on. And i noticed my headers were like a yellowish color, ( there painted white. Could my distributor be off a tooth or maybe the timing mark on the balancer is not the one for my stock timing chain cover? I'm kinda lost with the timing here, between the 2 different guys i spent $190, thanks for reading sorry its so long, i just need some help. Thanks again

you should have varified the balancer when building,now you have to do it.startwith a total of 34 timing.I would guess you might make 420 horse power

Here's the procedure....

You may experience better fuel mileage if you include an adjustable vacuum cannister and learn how to tune it.

Thank you for responding, and thanks for the input. I bought the crank, rods, flywheel, and harmonic balancer as a kit from eagle, if that is any help

A little-known fact is that there were 3 different dampers/tabs used on small block Chevies through the years, 12:00 Noon, 2:00 PM and 2:30 PM. Mixing them up won't work well and I suspect that you have no idea what orientation Eagle used. Just take a Saturday afternoon and run through the procedure I linked for you. It'll all work out fine once you've established a baseline.

Hi, yea i gotta get it straight, i think my stock timing tab is around the 2:00 positon. And i ask the last guy about my 650 dp carp if the jers in it are ok with this motor, and all he said was there stock holley jets. I asked him if a 800 holley dp would be ok for this combo and he said its to much. Thank you again for taking time to help me out sir

an 850 would work fine and a 750 would be ideal considering the cam choice

Honestly,it sounds like you mite shoulda stayed away from the 2nd guy.If he don't know anymore about timing than he does carbs,that may be your problem.You stated that engine was doin good until he worked on it.

My thoughts exactly. Anybody with a modicum of common sense knows that a small block Chevy can't use 48 degrees of initial and mechanical spark lead. The motor was probably in the area of 34-36 degrees of lead before the second guy came along, but didn't reflect that lead properly on the damper/tab. I'm thinkin' that the first guy realized that and timed the motor by ear and maybe a vacuum gauge.

Hi, yea the second guy is the one that told me when he checked the timing that the first guy did, his snap on timing gun said 48, but it was running, starting, and shutting off just fine. The second guy is a drag racer, he turned the timing back to 34, and thats where the car started running like crap then next day, motor seemed to have lost some power, i would shut it off, it would want to keep running, and my white headers, started to turn a yellowish color. Thats why im thinking the timing tab on my stock timing cover isnt the one i need. The second guy is the drag racer, he races a old buick and run's in the 9's all motor. Thats why i went to see him i thought he was a good choice, but i dont know, the first guy is just a regular mechanic

not a bad idea to book chassis dyno time.The timing can be checked by the computer/tuner.The power will also go down if the timing is too far advanced.check fuel curve and know what you have rather than guess
