Why start it with no exhaust? Even if you have oil pressure you couldn't hear a strange noise if your life depended on it! If that's a new cam you should be breaking it in. If I was a betting man I would give that motor 90 days before it takes a dump. When you spend that kind of money have someone that knows what there doing. Food for thought.

@paintonmyhands You should probably read the other comments before posting. A) It was impractical to mount the side mount headers and side pipes to the motor. B) Most articles out there show that studies have proven that they whole thing about bending valves when cool air is drawn in the exhaust ports is just a myth. C) Roller cam, not flat tappet... no break in. D) You lose your bet, motor has 2000 miles, 15 1/4mi passes, and almost 2 years of use with no issues. Runs beautiful. Thanks!

Forgot to mention compression ratio. It is in the 9.7:1 range. Again, thanks for any input you might have on the Edelbrock 800 cfm carb to be possibly matched with the new SBC Stroker Vortec (1 pc rear main seal).

[rmryder88]

@Querencias7 800cfm is a lot, but if you got it cheap you might as well try it. Like you said a good tuner can probably tweak to work with your set up, but Im no carb expert either so I cant promise that. Theres a formula to determine to max cfm required for your set up, I dont remember it, but I found this online and I think its the right one... for a street/strip carb: CFM= Max RPM x CID / 3456, so in my case my redline is 6000x383/3456 = 665cfm, which is why I went with a 650.

[rmryder88]

@Querencias7 ... I also went with the Edelbrock Thunder Series AVS, but like i said the 650 size. Im right on the border of needing more though. So, opposite of what you were planning, me and a tuner tweaked the needles and accelerator pump to get a little more flow from it and get it where it needed to be for my application. Either way, I think 800cfm is definitely big for what your looking for. For reference there is also a formula for Street ( .85xRPMxCID/3456) and Race (1.1xRPMxCID/3456)

I hate stupid people too, thats why I'd prefer you not leaving a comment. First off, this wasn't my idea, the engine builder chose to do it, and he's been building high performance motors for about 60 years now.  Second, I didn't have the headers yet to put on. Third, the plug wires were an old set he uses just on motors hes working on... so who cares what happens to them in the 30secs we ran the thing. Not knowing what you are talking about makes YOU look stupid.

i want that as my alarm clock!!!

[TheRoguelement]

Everybodys an expert ...Look guys you do what you want at your house and let everyone else do what they want at theres ok .. that way we all meet up at the track and see who's does what to who, this way we filter out the wannabees from the those who Can club and for god sakes fellas can't we just all getalong .....LMAO for 1320ft

[msd8283]

no pro builder would do something like that , it's upsurd

[devinhaney15]

scared the shit out of me

[MrBaSsHeAd94]

thats a good way to melt the distributer wires

[amck1941]

I like your set up. It sounds and runs good when you add your headers and exhaust. Also have the 800 cfm carb. Would recommend using a higher flowing air filter than the edelbrock 14x3.

[krazor8]

that is music... and the fire from the exhuast ports are the light show

[weponspec1682]

@smedfulful Not with running it for a few seconds. They wont get that hot in that short amount of time.

[SuBN01z3RaT]

@Rhage73 i had someone doing that to mine her name was 383 got some header lock bolts and ive not had a problem with bolts loosing up sense but it did blow the exhaust gasket clean out driving to my friends house and now i have a nice hollow sound from the driverside exhaust (the one that blew out) havnt figured it out yet valves are all adjusted correctly but one day ill get around to pullin the head off to put new ones on and ill find out then

[MrTJGentry]

Honey, I roasted the spark plug wires.

[smedfulful]

good ol boys with chevy toys love it but you can break a valve with cold air on a hot stem trust me done that
