340 to 372 stroker kit
For starters I have little knowledge in building motors so I’m trying to learn as much as I can.
Car is a 1972 demon;
I want to be somewhere around 450-500 hp. Would like to run on premium pump gas with/without octane booster.
Currently have a 340 block bored .060 over
55cc W2 heads
My father has recommended Scat but also wanted to see others opinions and experiences.
I’m in the process of this right now. I’m purchasing parts cheaply as the deals come in. There all new, just sold inexpensively for one reason or another. I’m down to a sonic checking blocks for slugs.
No matter what parts you get, kit or singular, they should all be forged. On the rods, the base Scat/Eagle Upgraded rods can hold 500+hp. You’ll be in good shape. A great kit is a Scat set up.
As far as larger stroke crank kits, there is good thought behind the idea of bigger is better. You’ll make more torque, but you really can’t get a head to “Properly” feed it. A ported W2 comes close for race applications. On the street, it’ll be fine. Considering your stated use of the car, ether stroker IMO is a win.
On my future engine and the car it will be in, a huge amount of torque is actually less desirable for a light A body & its target.
(Same as yours. A well done 318 will spin the tires without mercy for hundreds of feet.)
The induction will be a 6 pack and ported Edelbrock heads a/a roller cam.
Being you have W2 heads, keep the compression under 10-1 for pump gas. This is your problem with 55cc heads. You may be in for custom pistons. Also because of the bore size. It is not common to find a slug over 4.100.
A well ported set with 2.08’s will move the air. A cam duration @.050 in the mid 250’s will make the power.
