[blacstar]

where did u get the engine?

[BIG BLOCK 555]

it's all good now i have another engine and it run great thank god ,

i have a small problem for now ( im planning on using the clutch fan for some time before i upgrade to E-Fan ) v8 fan shroud i can't install it at all

v8 radiator cost nearly 160$ used , what to do about it ? buy v8 radiator or modify the fan shroud ?

thanks a lot guys

spend the money on e-fans

or just don't stick your fingers down there. it ain't a question of V6 or V8 - it's the 28" vs 34" radiator. all 1/2 tons had the 28" for the first few years, but you need the 34" for e-fans... or if you have the bigger one, get the shroud from a 3/4 ton
