i have a tvs 2300 front outlet with jack shaft on order. i'll be putting it on my 408. once i get it all together i'll be more then happy to share the dyno results. i have a 8 rib right now from my old setup. but like blownchevy is saying i think a ati 10 rib will have to be in order

 

ATI 10 rib?? is the ati 10 rib a overdriven crank pulley?

 

one fast ss I'd love to see the results of putting your soon to be TVS2300 front inlet wit jack shaft on your 408! If you don't mind me asking what are some of the internals of your 408? How much boost do you plan on running? Thanks.

 

time for another upgrade lol

 

i know the 8 rib is holding 16 psi boost fine and that set up is overdriven. Is the ATI crank overdriven also?

 

For the internals im running 4340 fordge crank, h-beam rods with arp 2000 bolts, JE deep dish pistions with 9.1:1 compression. chrommolly rings, clivet bearings. for boost i dont really know yet..i want about 750 or more hp to the tires. So maybe 15 psi? All i know is they put over drive gears in the back to get me where i wanna be.

If you have anymore questions id be happy to help
