1969 Plymouth Roadrunner

Ricky, ho una domanda per te.....



sto pensando seriamente ad uno stroker kit di 440source...potrei utilizzare il mio blocco o valutare un blocco 440 per non fermare troppo a lungo la macchina...



stavo cercando di capire che modifiche dovrei apportare e soprattutto se ? un lavoro che necessita di una preparazione specifica...



5) What other modifications or machine work is necessary to run these kits on an "RB" (413/426/440) engine?



For an RB engine, some very minor clearancing of the very bottom of the cylinder walls will usually be required. Sometimes you may also need to clearance the inside of the boss where the oil pickup tube screws in. Some blocks have more "meat" in them than others, so exactly how much you will need to clearance will depend on the specific block you are using. The larger the stroke, the "farther" away from the center the rods are going to be positioned, so the stroker kits with larger strokes will generally require slightly more clearancing. Most people who have enough technical skills to assemble an engine can do this clearancing in their garage with a die grinder in less than a couple hours. No actual extra "machine work" is required. Most of our smaller kits (511CI and below) usually will work with stock oil pickups, and stock oil pans. Also, don't forget you can't run the stock windage tray, a special stroker windage tray is required. We've got 'em listed on our site for a real nice price (of course..)



6) What other modifications or machine work is necessary to run these kits on a "B" (383/400) engine?



All of the above on the "RB" engines also applies to the "B" engine. This means some very minor clearancing of the very bottom of the cylinder walls and/or inside of the boss where the oil pickup tube screws in will sometimes be required. Some blocks have more "meat" in them than others, so exactly how much you will need to clearance will depend on the specific block you are using. The larger the stroke, the "farther" away from the center the rods are going to be positioned, so the stroker kits with larger strokes will generally require slightly more clearancing. Most people who have enough technical skills to assemble an engine can do this clearancing in their garage with a die grinder in less than a couple hours. No actual extra "machine work" is required. Most of our smaller kits (511CI and below) usually will work with stock oil pickups, and stock oil pans. Also, don't forget you can't run the stock windage tray, a special stroker windage tray is required. We've got 'em listed on our site for a real nice price (of course..) Our "B" engine cranks also come with the smaller factory sized counterweights, so you will never have to turn down the weights, which can be a problem with some of our competitors kits.





Grazie.....
