I wanst sure where to put this.. but,..

I need a longblock installed in my boat (98% sure its that), as i think the block is cracked. Does anyone know where i can go for the low low? i am wanting to get it done in the next 2 weeks.

i will need the longblock too as i dont have one.

its a 95 bayliner with a 350 mercruiser in it, with an alpha 1 outdrive.
