Re: 378 stroker

Same combo here. It's nice because ACL make a ready made piston to suit the Chev rods. Not an all out high HP combo, but it works well for me - 12.9 quarters on street tyres and street gearing.

Hidden traps? There is more machining work needed on the crank than most people will tell you. If you want it balanced up nice expect about $1k for the work.

Re: 378 stroker

I'm pretty sure it's not that dear anymore strokexd. I was quoted $400 to sort a 351 crank to 378/383 and $400 to balance which is pretty much a standard balance price.

The hidden cost comes with matching the rods, if you widden the journal to suit chev bigend width its expensive, however if you keep cleveland width you have to narrow the chev rods and bearings to suit which is a hidden cost.

Re: 378 stroker

Yeah my guy is pretty fair, but he was a bit suprised at the effort needed for matching rods, balancing plus heavy metal costs.

Either way my overall advice is it turns out more expensive these days than what is warranted when you can buy a ready made stroker crank. If I would do it again I would go aftermarket.

Re: 378 stroker

it shows me some 408 kits need block mods and some don't.

My mates that just went together needed nothing more the an oil restrictor kit. not notching at all.
This appears to be a different ballpark bottom end!
