Re: Big holley stealth ram question
for the fuel rails just go to summit and search holley stealthram and youll find the fuel rails that work and such. i think everyone here would suggest the ones with the adjustable fpr.
as for parts needed youll need to make custom fuel lines, random npt-barb fittings for vacuum lines, egr, brake booster, coolant fitting. also youll need a new waterneck because the tpi one will angle towards the valve covers. other than that id say its pretty straight forward you may need to cut the bracing under your hood for it to fit. im not too sure about that throttle body so i wont say anything about that. youll definately need tuning, higher rpms where tpi dies the stealth ram will need more fuel and probably need more but not as much at lower rpms.

Re: Big holley stealth ram question
for a 305 is probly gonna want a tune of some sort. factory TPI cars tend to run rich so a HSR will lean things out. Enough so that it may need extra fuel but my L98 didnt really need much more than just changing the fuel pressure
basically if you have the manifold and plenum, get the fuel rail kit from summit. it has the rails, and some barbs/connectors for the fuel rails
then your gonna want to get 6 feet of 6an stainless steel hose with 6an fittings. There are part numbers listed in one of my threads, hit me up if you want them if you cant find them, but you'll want the TPI hardline to 6an adapters, 2 straight 6an hose ends, and 2 hose ends that are either 90 or 120 degrees. 180 may work but 90-120 is best.
with fuel rail in place, you connect 2 straight hose ends to the fuel rail fitings, then use the 90-120 degree bends to attach the hose to the hard lines.
really simple. about 100-120 bucks in parts depending what you get for fuel lines. fuel rail kit i think varies between 180-250 depending on regulator
