Bigger bore & longer stroke always make more power.
E, you know what I am thinking...it's scary!......thanks for the advise. ............................Have you been a good boy and Santa has some engine presents for you, or is your brother giving you some lip about how much power his RR makes? The frugal mechanic would just leave it alone but in the end your decision.
E, I would like one of these!......will start looking or a 64 or 65...I am thinking another car to pound on if you can find it reasonably. Your Belvedere is to nice to make into a pounder. Next thing you will have to add frame connectors to your car and then the trans will give up the ghost, etc.
Went 10.60's with 906 heads. Yeah, they were ported to the max, big (for the day) cam, light weight pistons and plenty of gear. How fast do you want to go with it?
Cranky, the RB Block, has the 284/484 purple shaft ,.........yes I thought ,750 DP , Eddy RPM, or Indy dual plane..as advised by others...Don't believe I know what your combination is on that car. The larger valves would help for sure. Is your 750 a DP? If you have one laying around, you might even try an 850 base plate on the 750. The throttle plates are 1/16th bigger on the 850 plate vs the 750. It usually increases your throttle response and top end. Your heads are closed chamber, right? The 906's are open chamber so you'll be losing some compression but an exhaust valve that's .140 bigger along with the larger ports can help a lot vs the loss of compression. A cam change to better suit the new combination may be in order too....
Even if Sonny doesn't go for the big valves, for sure do the pockets. The factory back cut really sucks....Pocket port the 906's & put 2.14/1.81 valves in it.
I have '61,'62- 413 heads, I will keep them, I will keep the intake, I will get rid of the 600 weber,(for now and put a 750DP Hol) on it for a little more fun & should be ok with the BW-T10 & 355's...end of story (for now)....maybe I can beat a V6....lol....Super-bee_ski loves Sonny's car
Super-bee_ski thinks spending money for more speed is A-OK if that is what Sonny wishes!
When is enough enough?
That is the question....
Keep us informed
is going' with the heads that are on it! ----> 2206924 ./2.08/-/1.60/...413 CID...... with the 282/484 P.S., Cam/....3.55;s rear........the 4 speed, A 750 DP should do well............also, TTI headers & 3'in H pipe into flowmasters, stock rear tail pipes.......Mopar Orange ECU Box Ignition...etc
