Holley Stealth Ram ? Ok once again this is for my 3rd gen friend since he lacks the net. He has to replace the plenum and base plate on his 350 TPI iroc because they are not working. He wants to go the route of the Holley Stealth Ram from thunderracing but is unsure whether or not to get the normal one or the one for vortec heads. He has a good amount of $$$ to work with since he just got back from Iraq but I dont know what he would need to run the vortec one as oppossed to the normal Stealth Ram or how much and how many more parts he would need. Also what is the difference in power if he stuck with the normal Stealth Ram and heads rather then the Vortec Stealth Ram & vortec heads kit. He intends to buy it today because his car is not running and he needs this replaced.
Thanks

It all depends on the heads he wants to use. The parts required are identical, its just that the Vortec HSR has the raised ports necessary for Vortec style heads. If he is doing a set of heads at the same time then pick the manifold that matches the intake ports.

if he gets new heads, he should go with trick flows kenny d's or jus some afr 210's with the standard hsr.. that l98 will in 4 words, wake the **** up. if he jus has a stock l98 hell still pick up a crap load of power and itll make the power curve more like the ls1's. i hve an hsr im trying to get rid of btw

It comes on a lil slow in the bottom picks up around 2K and goes like hell from there I put together a 383ci with Some Edelbrock E-tec 200's I was purposely trying to kill some low end grunt 'cause it goes into a '65 C-10 (raed as NO weight in the rear) The motor is running 10.5-1 with a Comp Cams XFI Hydraulic roller it is supposed to make 540fwhp @ around 4500rpm and 485fwtq at around 3800rpm. All these numbers are Dyno Sym with really accurate input info. So I figure it'll be relatively accurate.
If you want TQ go with smaller runners keep the Compression over 10-1 and match the converter if your running auto.
Also Wants2go is right it's just a Weiand Tunnel Ram set up for F.I. and all reports are that it's good for at least over 50HP on a unaltered motor with some loss in the bottom for TQ but a HELL of alot more on the top the stock TPI is running out of air @ 4500 rpm and the HSR smokes it and climps farther than any SBC should ever go.
All in all he should be happy
