Have heads (kind of) now what?
I'm coming into a set of Dart Iron Eagle Platinums -
200cc 64cc SP 2.02/1.60 1.437D springs
I want to make the fastest pump gas friendly
street machine engine I can which will probably
end up in a AT G-body or 2G Camaro. Limited strip,
perhaps once or twice just to see what it "does"
and It has to drive itself everywhere it goes
Which block, valve train, intake recommendations
would you suggest for such a beast? I may be able
to change the head specs as well, but I'd rather not.
I have both 350 and a 400 cores available.
I've read a bunch of the archives and found some great
information, but not usually starting from the heads...
Thanks a bunch,
Sean

TO MUCH HEAD FOR 80 % OF STREET ENGINES.A LARGER CUBIC INCH ENGINE WOULD BE MORE FORGIVING.THESE SMALL SPRINGS WON'T LET YOU PUT MUCH CAM TO IT.YOU WOULD HAVE TO RUN A LOT OF GEAR AND A LOT OF STALL TO MAKE THEM WORK RIGHT OTHERWISE IT WILL FEEL LIKE YOU DON'T HAVE MUCH THROTTLE SIGNAL.
Re: Re: Have heads (kind of) now what?
I'm a little confused.
Dart claims the 200's are "ideal for 383-400 where excellent torque is desired without loosing the ability to wind it out occationally" The 1.437 double springs are 130#@1.800"/.620 max (Comp cams 987) They also have 1.250 single and 1.55 double available. If the 1.437's are wimpy why do they even offer 1.250's?
I really apprieciate all the input Im getting on this as I'm just learning.
Thanks again,
Sean

A LOT OF RACE SPRINGS ARE AT 1.550 DIA.MOST OF OUR ROLLER CAMS ARE SET UP WITH ABOUT 225 SEAT PRESSURE.OF COURSE I WOULD NEVER RUN THIS MUCH SEAT PRESSURE IN A STREET CAR.
