Hi everyone, I am looking for any information about supercharging a 400ci big block it’s a 1965 block it has the stock heads which have had a full refresh ported, new springs, valve seats, valves everything, block has been sleeved, oil restrictors to cam, eagle rods forged pistons, double chain timing chain, melling oil pump about 10.5:1 compression but I’m unsure about if any company’s make blowers for this or something used from the 70s any info helps thanks

 

Yes, do a search and you’ll find most people use the old Offy intake as a base. From there you’ll be able to find a blower. Or you could always do the Torqstorm system.
But with 10.5:1 compression you won’t be able to run much boost at all on pump gas.
And too bad you wasted money on the oil restrictors.

 

Check out Hampton Blowers

 

Mark , will the lower half of a 400E hold up well, even if the compression was lowered??

 

How much power are you looking to make?
