Really useful information, thank you.

I have done a bit of reading about it and there seems to be general agreement that it's a good idea to have a post pump filter even if you are using a Hydramat.

I'm torn as to whether to go for the Hydramat. It looks brilliant if making a tank from scratch but since the Bristol tank has baffles and a sump I wonder how much advantage it gives. I think the size you have chosen along with how often the car is used will give a good few years before it clogs but I'm more inclined to let some of the small particles go through the pump and collect in a 10 micron post pump filter that can more easily be replaced. By no means a criticism of your choice. I may well decide on a Hydramat but haven't made my mind up yet.

My shopping list currently looks like this:

Sniper 2 550-510 3xx $1300
Hyperspark distributor 565-344 $400
Fuel pump 12-169 $490
Coil 556-153 $45
Filter 162-554 $120
Filter brackets 162-574 $45

Total $2400

These are not confirmed choices that will definitely work together, just the best I can do for now after a bit of on line research. I am waiting to see how well the overdrive gearbox conversion works. If it's a success I think the Sniper will follow soon after.
