I'll start my BBC build soon and I am looking for ideas. Can someone give me a good proven budget big block combo that will get at least 650 hp.

 

sorry, no BBC help here.. but i just wanted to say, your 'maro looks bitchin with that mean rake.. oh, good luck on the BBC build up..

 

Thanks man although I'll lower it soon
Your Trans Am looks mean too

 

i just happened to be reading this months Chevy high preformance and they did a BBC VS SBC , they had a budge of 6,500 bucks for each

there BB was a 505 and made 622hp with 500 trq

was bored and stroked 4.350 x 4.250 , 10.5:1 comp

i auclt have the full listing of parts they used

which did not include the block they happened to have on hand

the small block they used was a 422 made 574 hp with 543 trq and costed the same price as the BB

 

waht about 454 stroked to 496 with top end and solid lifter cam?

any ideas?

 

hell i have no idea , i am to poor to afford a used 350 let alone a 454 =) i love my stinky 305 tho i just refuse to do anything proformence wise to it

 

Moving this from Tech to Engine Swap where most of the BBC discussions take place.

 

650 HP isnt to extremly hard to get out of a BB. Do some searching and youll find what you need.

 

I'll

I don't want to go extreme on hp because I want to build something reliable on good budget

 

stroke to 496.

11:1 compression

Good heads, such as 990's.

Solid roller cam, 250 @.050" and .700 lift

Team G intake 1000 cfm 4150 carb

 

thank you very much

 

496 with a roller cam and a good set of heads should be able to get you there. Then you can watch your driveline scatter across the road
Scat, Eagle, and World Products all have 496 bottom end kits pretty cheap. I'll be using the forged eagle or world kit for mine. I've heard nothing but good things about AFR CNC'd heads also.

 

I'll use eagle forged kit, dart 325 heads, comp cam solid roller cam, Holley 4150 carb and team G intake.

how is this combo sound?

 

What are the cam specs?
----------
ANd as stated, go ahead and get a good tranny, th400 or glide, and a 9" rear. Not to mention SFCs.

 

Duration 308/ 308, Lift .652/ .652 ,LS 110

 

I'll,thanks man

 

SOunds good. Do you have the .050" duration specs?

 

yes, 262 int./262 exh

 

That cam and those 325cc heads outta get you there. But dont expect great street manners

 

Agreed.

But, 650 hp and streetability is going to be about impossible to get NA.

That combo is gonna need a 4000-5000 stall converter and 4.30 or better gears.

If you want 650 hp and good street manners its time to look at forced induction. A very mild 454 with a procharger will easily do it and be streetable.

 

no need for good street manners I'll drive the car once or twice a month other than that I'll tow it to the track

thanks for the help
