Hey guys, last season I ran a hemi 212 limited modified on gas, with I believe a Tilly HL304 from Dustin at Comp Carbs. Awesome carb, fun little package.
Being on gas, naturally you experience much higher temps than with alky, so much so that at the end of my 20ish minute runs I could hardly even touch the intake manifold.
I've had the idea of getting my machinist to produce a plastic insulator that would sit between the head and manifold, in order to prevent the intake and carb from absorbing so much heat, is there any issues with doing this?
I've read on EC's website that with pumper/diaphram style carbs like the Tillotson, its important to ensure the carb gets the right amount of pulse from the engine, and if the intake runner is too long then this could be hindered.
Would it really be problematic to add say, a 3/8 thick plastic insulator between the manifold and head? Does anyone see any other issues this could cause aside from hurting the pulse signal?
Also, I would probably have to cut my own gaskets for this addition, what would be acceptable to use for that?
Thanks for any help/insight anyone can provide
