Response to Air pocket notion.........theory or real ?
UPDATE: here is a brief update for you; the conversion from standard Q intake to aftermarket standard GM style intake is totally possible, here are some issues.So far the only issues we have are clearance and steam venting.
Either you have it or you don't. In which case, if you don't have clearance and the height is a serious issuse, such as touching the underside of a cruiser fold down hatch (as opposed to a motor box that can easily be modified) then one must look for a very low profile aftermarket or stock iron intake to use.
The tapping solutions you have noted appear to be quite viable, so that is resolved. Any tapping into the intake area to reach the water passage can be routed to the stock location on the Q exhaust manifolds. (Why a concern about steam venting.......in short....because we are placing the thermostat now at the low side of the motor, there is a chance for air bubbles and a hot spot, and this concern exists even with the stock Q motor, and you will note the small copper steam vent lines leading to the manifold, so we believe this is also necessary for the conversion because the condition is exacerbated).
We will assume the thermostat will bolt directly from the Q to any other GM or aftermarket intake manifold until proven wrong, and until such time we confirm this with an actual project,. (Late breaking news.......The Q manifold had thermostat bolt holes 3 1/2" apart. Standard Chevrolet is about 3 1/4". Could be made to work.)
With the revised thermostat location there is a need to get water back to the front of the motor. This could potentially be done along the top of the motor if it is kept clear of the linkage and other things. There will need to be a hands on look at the plumbing needs, and it seems there may be proper diameter hoses with bends that can come off the t-stat, and also off the pump, joined in the middle with a length of copper pipe. We'll see how that goes.
So it appears anyone out there faced with spending $1200 for a Q intake "because there are no other alternatives and the supply is limited" could very easily obtain a nice performance upgrade by converting to a superior flowing aluminum intake for $200, then getting a new #1409 Edelbrock marine carb for $320, a phenolic wedge for $40, and a 50,000 volt marine distributor from Performance Distributors (our friend Steve Davis, of Davis Unified Ignition, DUI) and still have money left over for some gaskets, a new flame arrestor, and a $100 or $200 dinner with friends.
