The best stroker 408-416-426-435 combination in stock 68 340 block

no porting the stock 383 heads...
i can't change an intake,carb and cam and get over 100 hp?

Ive seen you struggle with this for years now. How do you make hp ?

Ultimately is the head. If you want 500 hp you need a head capable of supplying that much air flow. Then the rest of the combo is to work with that goal cam intake carb exhaust cr etc..

Now stock heads have way more potential than the stock hp numbers.

Take the lowly 318 head. It has at least enough flow to make 300 - 325 hp and probably even more if you crank the cr and duration.

So how do you get that 300 - 325 hp out ?
The same way you would any engine. Cam cr intake exhaut etc..

Lot of times were stuck with factory cr which is gonna limit cam choice which is the 2nd major contributor to power. Because we know 4 bbl and headers only do so much on there own.

Theres no reason we cant add 100 -150 hp especially to engines that dont even make 200 hp factory.

Th only real difference between the 300 and 380 hp create engine basically is cam.
