At 17 psi got to be at least making hp in the 800's.

There Is now, guess there was a glitch or something.

Got a link ?

Interested in the answer, blown or not the CR should remain 13:1 so I imagine you should be able to, probably with the right fuel.

408 with trick flow heads is probably around 500 hp itself plus you'd think 150-200 hp for the blower, which be 650-700 hp.

Really ?? If I'm wrong that's fine I just like reasons so at least I can learn from my mistakes :)

Supercharged builds you hp and torque cubic inch only gives you torque.

I'm not trying to argue either. But Everyone seems to think small engines is the only way to get mileage but it take a certain amount of fuel to get your car moving (weight) no matter the engine size. 20 mpg in town is a hard number to get even a lot of modern cars (similar weight) with all the...

20 mpg in town or the highway ?? I've had dozen of /6 cars I wouldn't brag about any of there mileage my 318 5 Ave gets about the same. If you don't think you could get 20 with a mild 360 then start with a 273 still miles ahead with power potential over a /6. 273 is only 50 cid bigger but it has...

Yes its do able with a turbo, but id go turbo 360. Cause the 90% of time you'll be just driving off the engines own power.

Not without turbo or some kind of power adder. Slant 6 head is the weakest part, untouched your lucky to make anyway near 200 hp ported could make up to 300 hp but to get mileage you want to be in the 0.8:1-1:1 hp:cid which is 200-225 hp over 250 hp you'd start to have more of a street strip...

Just seen ya driving down the road on Hwy 2 thought I recognized the car, looks awesome :)

How did he build 10:1 cr with cast pistons ??

Bore size is the ultimate factor on power, piston speed if taken out to the max rpm each combo will ruffly have the same power potential. But since you put a 6500 rpm limit the largest Cid will have the most potential. 400 block is the best choice for sub 500 inch engines but over 500 I'd go...

I read an article that said to degree it to what ever gives the highest cranking pressure seems to make sense. But the best would be trying different degrees on the dyno (or track) and see which is best every thing else is a guessing game.

Since this is a street car how much CR should I go with 8:1,8:8,9:1 with pump gas and how much boost you can get away with. It will be intercooled and maybe running water/methanol injection. I'm thinking higher CR would be better for a street car because I would be drive more on N/A engine than...

I'm not against making 500hp at the wheel especially at 7 psi, the 273 in N/A form probably be will be making 250-300hp at the crank

I've been recommended to use Twin T3/T4 any certain Specs and Brand I should be looking for? This will be a street car

I'm only looking for 500hp at the crank

I was thinking of an air wolf headed 360 for my 65 Cuda and looking for 500hp/500lbs-ft, but as I'm dumping $120 for just over 200 miles in my 5.9l Jeep, lucky I live a only couple of miles from work, I don't really need another pig on gas also got 1980 Bronco with a 400. So I'm think of...
