A couple of clarifications on the forged crank deal.
1) The material will be a 4340 non-twist forging.
2) The crank will NOT be cross drilled. It will incorporate the latest technology in crank oiling, scoop oil holes and straight shot oil timing. This process pressurizes at the low pressure part of the stroke and traps the oil wedge during the high pressure part of the stroke. Cross drilling forces the oil pressure to try and overcome combustion pressure of 1000 plus psi which and translate to 10,000 psi at the bearing. This force will push the oil right back out the journal and send it to another place in the crank. Straight shot traps the oil and it has no where to go but to the rod bearing. It is the best oiling system currently available for low or high HP motors at this time.
3) The 3 inch main cranks will be available in 4, 4.25, and 4.5 inch strokes with 2.200 rod journals.
4) We are hoping to produce a 3 ¼ main but do not yet know if it will happen. If it does it will probably be available in a 4.250 stroke only.
5) Target price is $1095.00 but is not definite at this time.
6) The cranks will be gas nitrided, no induction hardening
7) Neither BOP Engineering or All-Pontiac.com are taking orders at this time
We will have more information soon so please be patient. With that said we are pleased to be working together with Frank and Bob to bring high quality racing parts to the Pontiac community.
