77 engine build

[roland witherspoon]

Looking for advice, I’m building a 77 for pulling, looking at a 1550 block and head. Any other things that are a must for this set up. Thanks in advance

Do your rules allow 7 main engine? If they do you can drop a healthy 310 in and be reasonably competitive. 1550 engine isnt going to do that much for ya.

Hi Tom
Natpa does not allow a 310 in a 77. That’s what I have and they said I had to take it out.

What division are you running? If div 3 maybe you should consider doing an 88 as it looks like you can run 310?
Oliver 88/Su88/880 models only are allowed – (7) main blocks; (12) port heads & blocks 1600 – 1800 series. Waukesha 1100/GK series heads and blocks. With a little work you can get an 88 down to 4000 pounds, even with 18.4x38,s on steel rims.
