HOW TO MAKE 600-HP BIG-BLOCK CHEVY POWER. FROM CHEAP, JUNKYARD TURBO 8.1L TO ALL-MOTOR 496 TO SC 454
HOW CAN I MAKE A 600 HP BIG BLOCK? CAN I ADD BOOST TO MY 8.1L GEN 7 BBC? WILL A 496 STROKER MAKE OVER 600 HP WITH STOCK, IRON HEADS? CAN I RUN A 6-71 BLOWER ON MY JUNKYARD 454? HOW MUCH POWER DO HEADS, CAMA ND INTAKE ADD TO A JUNKYARD 454? CAN I RUN BOOST ON A GEN 6 454? HOW MUCH IS A HEAD SWAP WORTH ON A 496 STROKER? CHECK OUT THIS VIDEO WHERE I DEMONSTRATED THREE DIFFERENT METHODS OF EXCEEDING 600 HP WITH A BIG BLOCK CHEVY. THE COMBOS INCLUDE A TURBO 8.1L, AN ALL-MOTOR 496 WITH STOCK, REC-PORT, IRON HEADS AND A GEN 6 454 EQUIPPED WITH HCI AND A 6-71 BLOWER (AT DIFFERENT BOOST LEVELS).

I’m so glad rich is doing videos on the gen 7. It’s much needed information.
This is exactly the video I needed. Just acquired a square body with a 454 that needs a redo.
The 496 with the 088’s is an impressive combo, good numbers with a GM casting cylinder head. 👍🏻
Thanks for posting pump gas friendly blower options for us street cruizer guys
My old 468 I built made 610hp/555ft lbs with 93 octane, 10.2:1 compression and a 850 double pumper carb. I used a set of unported 308 iron eagle heads, victor jr intake. and the #7 rocker coming off at the end of the Dyno pull. Didn't get to make another pull. 👀🤷 Great video as usual!!🤟
You should include cost
BBC 🤯
It be amazing if you did a build with a 2 valve 6.8 V10 engine
Turbo 8.1 is a torque king
On any of these combinations it would be nice to see the price difference among the three
We need a big bang 8.1!!!
If you're going to use the stock manifold, you need to take it off and modify it first. The PCV system bleeds directly off the bottom of the manifold and will pump your cylinders full of excess oil. That needs to be plugged.
What do you do with all your engines? Save them for project or sell?
Thanks, Richard. Any way you could show us how to do a 700 hps in a Chevy BBC 427?
Personally I blame squirrels
Injection is nice.
Where does a person get the edlebrock heads and what is the price? Great video!
Planning on building a gen 6, 496. Would afr 265. Heads and that xr271 cam you used, and a air gap dual plane be a good combo for a weekend driver truck application?
So in a 496 build for a 4x4 dually hauling heavy loads would you go with a steel crank or would a cast crank do
Hey Richard what was the compression ratio on the 496 with the rods, pistons and the 088 heads? Made over 600 hp. I currently run a 496 with more or less the same rotating assembly, highly ported 088 heads and a marine cam. In my situation I ran out of money and couldn't afford a nicer roller cam. Used a flat tappet comp cam. 544/547 lift 240/240 duration ( that's a close number on duration, can't remember exactly) with a 112 lobe separation. Think I'm close to 600 hp at the flywheel? Have a Holly single pumper 750 4150 flange on it now I also don't think is enough carb. This setup is in a 24 foot boat. THANKS!
