5.7L Hemi, 1968 Barracuda.. Opinions.

I have a 6.1 hemi in my 69 barracuda, with a XFI 273 and a holley 650. It's reliable, starts regardless of the weather, and it's fast, plus it runs smoother than the w2 headed 340 I replaced. The 340 had a solid .528 cam and made similar power, but the hemi's torque comes on instantly, and doesn't go away. You can buy expensive new parts for a 340, or beat old part, but even used the hemi has almost all new parts. The w2 heads flow 270 cfm ( and that's a race head ) the 03-07 hemi flow 269 cfm. Reliability is the key. The new hemi is like a built 340 in it's stock configuration, as you build you sacrifice too. Hands down the new hemi wins.
