The '68 Valiant has a stone-stock 170 Slant and I intend to largely keep it that way other than an ignition upgrade.
The '69 Valiant has a stock-stroke steel-crank 340, +.030" w/forged 10.5:1 TRWs. It's balanced (I don't know if the block was blueprinted) and sports ported 15° 65cc W2 heads, a Victor W2 intake, TTi headers and Holley 830DP (9381). The cam is a custom Lunati solid roller w/.586" lift, and an Ignitor III lights it all off.
My Challenger's engine (does that count?) will also be a 340. That block is fully blueprinted @ +.020". Pistons are by SRP, rods by BME, and the crank is a forged MP unit. I have ported T/A heads & rockers along with a complete OE Six Pack setup for the top end, an MP 284°/.528" solid cam, and a programmable distributorless ignition for spark. I still need to get the rotating assembly balanced; I'm waiting on dowel bearings for the rods. Yet another 4-speed car.
No real plans yet for the eight other 340s, the 360, or the 440 currently darkening my garage...
