Good choices. I just finished upgrading my '
stang. Here are my $0.02:
AFR - good pick. The 185's, as mentioned, are better for obvious reasons. Think of the future and the possibility that you may, one day, want to go bigger; 347, T/C, S/C. If you already have the 185's, you have less to worry about.
TRE perf - I looked at their stuff and decided to go with CHP (Coast High Perf). Got a way better deal (331, forged internals, H beam c.rods, AFR 185's assembled, Scorpion rockers, Comp cam, timing chain, ARP everywhere, Cometic gaskets, and delivery for $5000.00
Intake manifold - I hear that Holley Systemax is the best there is more often than any other intake out there. I forget but there was even an article on it. However, Trickflow and Edelbrock also make good ones too for less. I have the Edelbrock.
Hope it helps....P.
