1991vert said:so what about 185's. i was reading in another thread that you said victor jr. heads are better than 185's. i dont really want high RPM power. i'd like the car to be streetable also
89CopCoupe said:One of "our" magazine companies ran a 165 and 185 comparison on a 347 with all other engine components being the same, and according to the mag, the 185's only made about 20 more on the engine dyno with torque being so close it was negligable.
Porting the 165's would help a little if done on a CNC machine, but having them hand done could possibly produce adverse affect and would be a bit of a gamble ... a man just cannot produce equal flow characteristics as a machine and the factory trial and error.
Since you have 165's right now, I would keep those if you build a street 331 ... if you build a 347 I might consider selling the 165's and getting the 185's.
However, since you are making 302/6, 165 power right now ,here is my suggestion.
CHP347 balanced-knife edged-alum girdle-windage tray, 185's(58cc), RPMII, 70tb, 30lb injectors, Comp XE274HR or custom with a split pattern ... Duration around 222/228, lift around .550", 112* lobe
This combo will make enough power to make street driving quite entertaining

1991vert said:my first debate was between a blown 306 and a blown 331. the heads are the limiting factor and i just dont know which to do. i might have to pass the sniffer if i dont move within the next 2 years, but i plan on movign to FL...hopefully that falls through.
1991vert said:are the edelbrock top pieces interchangable with the professional products "typhoon" intake?
Some counties in florida dont do emissions.1991vert said:ok well im thinking about a either a probe stroker kit or a scat with all forged internals and this WILL be going in a dart block.
