Hey folks.

I have been trying to find information about using a HR Block/Bottom End with the DE Heads for a Road Race Motor.

It is my understanding that the HR Block is significantly stronger, and that the difference to do a HR swap are many and too costly.

So is it possible and cost effective to build a HR Bottom end with eagle rods and forged pistons, and slap on my DE Heads?

I read a thread that GTM is building a Crazy Stroked HR Bottom End, and I have already sent them an e-mail for information.

If anyone has any information, it would be greatly appreciated. Thank You

 

If you are planing to build the HR bottom, then just build DE. Its same..

 

agreed if you are going to use a stock HR bottom, this makes sense, but if youre building...why try to do something thats never been done, and create yourself a mess of one off problems...

build a DE and call it a day...or do the complete HR swap.

my two point five cents worth.

 

Build teh DE. Lots more after market support for it than teh HR.

 

WOW

 

According to GTM, the HR heads flow a lot better than the DE heads stock to stock. Stick with one or the other to save yourself the headache.
