I don't want you to believe me, that would mean that you have made a smart decision, and at this point that is beyond your scope. I was around Jeff's truck when it was first painted as the "Silverline" truck, back when it was running an 11. 8 with S300 non ET and HT3B twins, then it went to a SP66 and nitrous, and now back to a PS66 and HT4C twins. You have no knowledge of anything pertinent to the conversation, I never stated that Jeff was running headbolts in "his" truck, I said that you would be suprised who is. I would be embarrassed to be a shop owner if I displayed your level of insight, but I will gladly keep proving you wrong if you desire.
Your quote from the other board was Jeff's Silverline truck.
You say overbuild, but the fact is you don't know where the boundary is for stock parts because you don't care, you sell parts.![]()
( 0 plate, 370's, 191 delivery valves, 18* timing and a 180hp pump, what's that 375hp?)
Most of the projects I get are on a budget, and often they do not have the time or money to spend on parts they do not need. For instance, '96 automatic with 215 injectors and 2000 rack plug, 400hp 15* advance with a retorque on the stock headbolts - has seen 57psi @260K miles and no failures. This is one of many cases where proper procedure and maintenance will overcome failure. Why is this so hard to understand?
Even with the improper spray angle the 370's have and a properly studded head I believe Jim Fullmer went beyond 700hp.
With what your doing your setting yourself up for a class action suit from your customers with retorqued bolts when they all will eventually have warped heads.
Jim has 155* pistons, so they did not have the improper spray pattern.
