Gearbanger, you ran 113 mph with a 12.70 ET. If you could hook a 1.60 60' you would be running upper/mid 11's.

Bare but ported to 310cfm is 1795 - pretty good deal - I think.

Not sure how much it'll cost me on top of that price to have ready to install.

I was thinkin of having Dave at SD port and finish some (if i can find someone to buy my 670's to help pay for the new heads), we will see. Have to wait till spring, too much on the go right now.

I believe in checks & balances along with + & - so.....
I bought a set of KRE 74cc-310 CFM d ports. They were flowed by a reputable engine builder prior to installation. Not really to "check" them out but rathet to compare to my Butler ported 670's I was taking off. They flowed 298 @ .600...very close to KRE sheet..Proof was in the pudding.. With the KRE's and change to a mild solid flat tappet cam it ran a 11.68 on madin voyage..in Drive... Best avreage ET's had been 12.4 - 12.5's... I was pleased...When my motor exploded early this season it drove #3 piston up into head....only sustained a small "scratch"...cleaned it up with a mill and replaced two valves. I personally have had good CS with Jeff at KRE.. I just ordered a set of the 74cc 325 CFM heads for my 505 build...as stated in another thread..I can't speak for others...just my own experiences and opinions... One thought.....if KRE's flowbench shows the numbers that is on their sheets,that doesn'rt mean KRE is decieving anybody. That what their machine says...My opinion again...;)

Troy- with 74cc on a 505 are you dishing the pistons? What final CR?

ponjohn......no dishes for me. This is going to be a strickly track motor.Haven't figured CR yet, but it will up there To make the most out of a solid roller cam..... I believe my CR with the 74's on my 462 was about 11.8-1 prior to milling .030..Maybe 12+ now on 462. I got the smaller cc heads as Jeff said I could have them opened up to 87cc down the road if needed...

"Gearbanger, you ran 113 mph with a 12.70 ET. If you could hook a 1.60 60' you would be running upper/mid 11's." I must be doing something wrong. My Cast Iron Number 16s never flowed over 240 cfm (not 310 cfm), were heavier naturally vs aluminum heads, and the car went 11.55 at 117+ mph. No offense but a 310 head should make over 600 hp if the engine was right. (Like mid 10s on the et). Tom V.

Car was my 64 GTO convert (before I hurt the frame) LOL.
Car would do 1.62 60 ft times if the tires would hook. Small 9" tire as I did not cut up the car. Yes, it had a good engine in it. Drove on the street BUT not a trip car. I averaged 5 mpg on a 150 mile trip one time. That engine probably never made over 450 real HP. Tom V. Fat Finger! LOL

Tom you're also assuming the car was cam'd properly. Maybe he has 310cfm heads with an 068 cam. No way it's gonna make 600hp with that cam - naturally aspirated.

Agree! You are correct on that coment.
