No qualms with 4500 being better, more efficient etc.
No qualms with with your position on that company- we share that position.
I don't blame the technology the Law boys created on the company selling some of them and, guys that have no choice but to run 4150 units have to find the best answers they can - thats all.
I would personally rather have 4150 with boosters than one with spray bars and, for wot competition the twin meets a lot of needs.
Now that there are parts available from other companies for the builders the issues we dealt with don't have to be an issue at all.
I cannot deal with Indy Racing heads- tried, its basically the same deal as we went through- it was "stick a fork in me, im done " real quickly.
That said, we do use some Indy parts- we just don't call indy .
I can appreciate the technology without dealing with lug heads.
