BBC Bowtie Head Question
Posted: Wed Jul 26, 2006 5:07 pm
New guy with question here. Recently took a Mark IV Bowtie block and a set of heads in trade. Currently 509 ci w/ 4.5 bore. Considering putting this engine together and running on alky with a tunnel ram and Enderle Bird. Question is about the heads. They are GM p/n 12363425, casting #14044861 alum heads. These are "open" chamber heads, about 115cc. Int runners are 380 cc rectangle ports. The 2.19 int valves have been changed to 2.25 and ex are still 1.88. Ex port has a "vane" in it. The literature calls it a "w" port. Bowls have had a little work and int ports were matched with something previous owner ran that I would have to change a little.
Intended use is low 8 sec brackets and NEII type stuff in 2100 lb altered. Am I going to be able to make any power with these heads without a lot of additional work or should I start right out with one of the better Canfields, Brodix, etc. and e-bay these things?
Thanks in advance for help.
