Hey lads, I'm toying up buying a 2nd motor ( project motor ) to swap into my 1200 eventually, I know what's generally involved but I'm confused when clearances are talked about, I want to run 14+ psi so I know I'm gonna need forgies,rods,bearings, I've heard of a few brands and not scared to spend

Is it worth just getting a shop to put it he block together with rods, bearings n all?

Also if I bored out the block can I go ca20det and which pistons can I use?

Cheers boys

My opinion and what I have done is sorce the parts you want to go into this motor abduction take it to a engine builder! Get 20-40thou over pistons, your rods, arp bolts and let him get the bearings as they may be different sizes after the crank gets linished.
I didn't want to spend 3-5g on parts to get the slightest clearance wrong and loose parts in a let go . A standard motor wouldn't be so bad but not after a forget set up is built

After the machining is done the engine builder charges about $500 for assembly and with that $500 you get warranty and pice off mind
