Hi there all,

indy valve covers with spray bar oiling
Smith bros pushrods

I am waiting for more info on the engine so as soon as I get it i will post it.

What I would like to know is are there any known problems with this bore, stroke, block combo and what are the heads like.

Will be a street/strip car so would like to know as much as possible about this combo as I am new to big blocks.

Any help/info would be greatly appreciated.
Thanks in advance
George.

I run the same combo , only difference being 4.562 bore/4.625 stroke , i take it this is the raised cam block? , i run the 605 on the street with no issue , only problems i've had have been with the indy spray bar setup , just gott pull the valve covers regularly to check pushrods , can be a pain when using the larger type MSD distributor (nitrous) , other issues being valve spring temp/cold start.

Are those pistons vertical or lateral gas ported? , only issues i see are the gas ports getting gummed up with street use.

Good luck , a few good parts in that motor.
