Still struggling with what direction to go on this car. Spoke to a couple builders I like, but both would stretch the budget (need some $ left over for Tremec 5sp conversion as well). Fishing for opinions on this 400 crate. According to blueprint, plenty of vacuum for street... https://paceperformance.com/i-23142...turn-key-crate-engine-with-chrome-finish.html Advantages: aftermarket block with splayed caps/ priority oiling, etc Price/ warranty Plenty of power Airgap intake perfect height with dual snorkel and looks / performs well More cubes but the heavier block should help keep her cool using existing shroud/ radiator Shortblock is dynoed at BP Disadvantages: External balance Cast crank/rods & hypereutectics Exhaust port shape- may be problem for hooker super comps that have been installed on the car since the original engine was pulled. Cam borderline for street? Don’t care to touch that hot stove again! Looking at 383/415 from ATK as well, but leaning blueprint due largely to new/ more sturdy block and increased cubes. Roughly same money as motor above but ATK is overbored, seasoned block. LS is out because the car is for the most part original w/ docs, and I’m hoping I can package the car with the original LT1 someday. Car has 3.73’s and will not see track. I’m specifically interested in opinions on this cam. I believe it’s a comp cam. Thanks!
