340 max camshaft with exhaust manifolds
Here’s mine, I have more compression that you would want, but have run 11.39 at 117. Stroked? Yes. More compression? Yes. Solid flat tappet through manifolds, yes. The manifolds like more lobe separation.
I think mine is a 78 360 block bored to .040. With Icon forged flat top pistons .010 in the hole. Scat h beam rods and Scat 4” cast crank. The heads are x heads ported by Dwayne Porter of Porter Racing Heads. Flow about 274 cfm intake. The cam is an Engle flat tappet intake .557 lift 245 degs at .050 lift. Exh is .551 lift with 261 degs at .050 lift. 112 degs lobe seperation. Intake is stock 68-69 340 manifold with the divider cut down and smoothed out a bit. Stock hipo 340 exh manifolds. Eddy 800 cfm AVS thunder series. Two fuel pumps. A big Carter mechanical and a Holley red pump back at the tank with Holley hydra mat inside. Mallory billet distributor and MSD 6al. 904 trans with Cope RMVB with a PTC 9.5 “ converter. 4:10 rear gear in an 8 3/4”. TTI 2.5” exhaust. Slant 6 front torsion bars with QA1 R’s on the front and 1” over arched leafs on the rear with QA-1 double adjustable rear shocks. Car is original 68 Barracuda 340-s Fastback, weighs 3353 lbs with me in it. Tires are f70-14 polyglas redlines. Best run is 1.60 60’ 11.393. Best mph is 117.22 Shifting at 6500 rpm. Looks box stock. Oh converter flashes to 3400 rpm
