Thanks!

You can probably get some ideas from guys on here, but I would suggest that you would still/eventually PM "rmbuilder"...he has the knowledge, experience, and integrity to help you get set up with the right head/cam combination for the cubic inch size of your engines, type of application, etc. He has helped me with my combination, and several others here.

KAAMA has a good plan, I may add that you have a good induction system you may want to add some stroke to the engines and gain some CID. That extra .250" of arm does wonders.

Re: More Power
 

At some point the blowers themselves become the bottle neck. Will 250 blowers fit the intercoolers you bought?

Re: More Power
 

im not sure if the 250 will fit the coolers,i will find out today,thanks!heres a pic of what i have now

Re: More Power
 

It is my understanding that increasing the cubes with the same blower will drop the current max boost some since we are now feeding a larger volume. I would want to know if you would still gain horsepower with the lower boost if you keep the present blower.

Re: More Power
 

I'd say scrap the old induction and drop on some 8-71s at around 7-7.5psi with some roller cams....
Come to think of it, MSD ignition and spinning it at 5600rpm should help too.
Forget the rod deal, a .250 longer rod may give you 5-7hp.

Re: More Power
 

so i guess get rid of the induction from intake up?what about getting new heads or flowing out mine,which way is better?

Re: More Power
 

What did you find out about a larger blower fitting on your present intake?

Re: More Power
 

I wouldn't worry about the heads...good enough for the 454CID.
I might even take back the cam swap idea....to much work and $ for a 30-40hp gain.
The 8-71's should do it.
