Question Stroker Question

A quick question I am hoping some of you guys would know the answer to. I may have an opportunity to purchase a 347 stroker crank at a great price for my EF XR8. The guy who is selling it told me that I would not need anything else done to the engine. Is this true? Is it a matter of just having it installed and tuned? It just seems too easy, as I thought there maybe the need to change other things in the engine?

Cheers

Damian

Re: Stroker Question

You need to notch the bottom of the bores to allow for the rod angle,need different conrods,pistons
I am sure i have missed somthing but thats about the basics

What ever I have will never be enough !

Re: Stroker Question

You need more than the crank, you need the rods and pistons as well. Then the assembly needs to be balanced.

Ps
I just noticed you have an XR8. Most striker kits are 28 ounce so you will also need a new balancer and flywheel.

No mate I have just had mine ballanced, they machine flywheel back to 28 ounce [or whatever] .. Std ballancer & flywheel...

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

Re: Stroker Question

Thanks heaps for your info, There are always people in know to help out here! It seems I will need to ask him a few more questions. Also is there any particular stroker set (remaining pistons, rods etc) that I need to purchase. Am I better of keeping to a particular brand for quailty sake, as I am not sure who makes the crank.

Cheers

I'd hate to see what your standard 50 ounce flywheel and balancer looks like. My lighter 28 ounce looks like swiss cheese!!!

Should funds permit, it's always a good thing to go for a steel flywheel and balancer in a performance application. It's also necessary for racing - should you feel so inclined.

Steel flywheels are also multi-drilled to suit a wide range of clutches - something that will come in very handy when it comes time to upgrade.

Re: Stroker Question

I'm also interested in stroking a 302W to 347. Can you buy whole kits, where from, how much, and what are the proven kit brands to go for? Also, is it even worth doing this mod? What work has to be done to the block/cylinder bores if any?

Cheers
