I'm considering a few 'technical adjustments', has anyone any experience of the items in the subject line?

Crane cams are very respected, never used those rods or pistons though.

id say for the price you pay for those will almost double your smiles . go for it .

the eagle rods are pretty good , being H beam .

if its a cutsom application - try to pick the lightest piston with the the highest pin bore to allow a good sized rod in there . Revs , revs , revs with that sort of setup .

Im using a similar approach but with stuff that can survive high boost pressures , so its always wise to pick for your particular application .
