Thanks Guys was originally a 253 but ditched that in favor of some chevy muscle and none of that 350 rubbish.

Stepped it upto a 400 with flat top pistons double hump fuellie head ported polished and angle decked.   Turbo 350 into a dirty old Ford 9inch.    I kept a standard manifold as i was planning on driving it on my P plates    I really need to upgrade not sure if ill go tunnel rams for looks or a nice alloy edelbrock performer.    Sadly a blower is out of the question the compression would be to high
