327 THUMPR CAM FIRST START AFTER REBUILD

THIS IS THE FIRST TIME TRYING TO START MY 327ci SMALL BLOCK CHEVROLET AFTER REBUILD. THIS LITTLE BEAST HAS BEEN BORED 0.40 OVER WHICH MAKES IT A 333ci I PUT A SET OF ALUMINUM 2.02 1.60's HEADS WITH ROLLER ROCKERS. IT HAS A RPM AIR GAP INTAKE "POLISHED" WITH A 650CFM HOLLEY CARB, H.E.I & FORCE IGNITION BOX. MUTHA THUMPR CAM, TRUE DOUBLE ROLLER TIMING CHAIN, ALUMINUM .PULLEY'S ALONG WITH EVERYTHING ELSE. THIS THING SHOULD BE 400HP EASY. THE MOTOR STARTED GETTING A LITTLE WARM ABOUT HALF WAY TROUGH THE BREAK IN SO I CHOSE TO SHUT IT OFF, LET IT COOL & GET SOME MORE COOLANT IN IT AND ANOTHER FAN ON IT. TELL ME WHAT YOU THINK OF IT.

I have about $6000 into my motor maybe a couple hundred more but no more than $6500 and I am still running strong til this day. My motor is pushing well over 450 at the crank and it has no problem spinning 8000 rpm right now! I would have to say they are all wrong this is proof brother...

great video man, Im planning to do a similar build up and I wanted to know how that cam would sound in a 327.

@jungleboyent

Check out my other videos and you can hear it a whole lot better, As far as performance goes I just had my truck dyno tested and i am pushing 475 hp at the crank @ 7000 rpm. My speed was 140 mph with 4:11 gears he still could of went more than 7000 rpm I seen my tach get up to 7800 rpm as i started to go sideways @ 40 mph so I got out of it. It was not missing a beat either, it is a great setup thats for damn sure. Now if I could get traction we would be in business.

Nice! Break in that cam right. Sounds healthy what brand heads did you use?

[My74C10]

@augustoescobar50

Thanks man! The heads are 2.02 1.60 Pro Comp's with 1.5 Roller rockers.

@My74C10 Nice!!! how do you like the pro comp heads? Was thinking about a set for my 302 roller.

My speed was 140 mph with 4:11 gears ? What? Really? In a truck?

hey im looking at buying my neibors 68 camaro that has a 327 sbc (all stock) and was wondering how much money it would cost to build a 327 like yours 450-500hp 7-8k rpm? im seeing alot of people saying it cant be done unless spending about 10k and still be reliable.

Nice to see someone that runs their engine at 2000+rpm upon initial start-up, like they are supposed to. Wish I had a dime for every video that is labelled "first start" and shows the engine idling at 800 rpm or less, during the entire vid. Your knowlege and investment have resulted in a sweet-sounding small block. Looking forward to viewing additional footage of this engine performing strongly on the test track.
