Mild 408 W/1.88" Valves
Here's a quick post about a just finished 408. Customer brought it to me with blown head gaskets and a number of other small issues. He just wanted it to run well and didn't really care about overall power, just wanted a nice cruiser for his new to him E-body. Oh and he wanted it red, it was blue. Pulled it apart and somebody spent money on good Icon forged pistons but in a stock 4" bore with a worn out 1977 360 block. They even balanced the SCAT 9000 Cast Steel crank internally with 5 slugs of Mallory. Wow talk about spending your money in all the wrong places. Anywho, bored/honed .030", decked, line honed etc..... SRP flat tops went in and turned and rebalanced the crankshaft. Re-used the Comp XE hyd flat, revalve jobbed the '974 heads etc.... Got it on the dyno and it runs great, 15" vaccuum, 50-60psi hot idle and it makes exactly what it should make, about 400hp/470 tq. Very anti-climatic build but it should move the E-body just fine. This is my first 1.88" valved stroker and it behaved as expected--peak power flat lines @ 4900-5300rpm. I forget the cam grind number but I believe it featured 224 @.050" on a 110. Carb was a nice simple 650 dbl done by GB carburetion << the best. J.Rob
