Clearance Grinding
Unlike the common kits for small blocks, these require no clearance work in
factory blocks. Aftermarket block sometimes need a very small amount of
grinding in #2 and #4 main bulkheads - 10 minutes work at the most.
Why do Survival kits include race bearings?
For extra clearance for the crankshaft's journal radius. If you used
passenger car bearings you'll bolt the kit together and find no side clearance
between the rods - and the race bearings are stronger too - giving an extra
margin of strength. All race bearings are perfectly suitable for street use.
Why do Survival kits include internal balancing?
Because it's the right thing to do. Internal balancing is easier on the crank
and bearings at high RPM and high power levels. Even the Scat 3.984
stroke 428 replacement cranks are designed to be internal balanced, unlike
the factory pieces. Internal balancing allows you to run readily available
dampers, flywheels, and flexplates from a 427 or a 390 without being
concerned about disturbing the engine's balance.
H beam or I beam rods - which to use?
We generally prefer the Scat H beam for most FE stroker applications. They
are a bit beefier, and the machining and finish seems a touch nicer. We've
run H beams at over 750 horsepower with no issues at all. I beams are a
great alternative for street oriented engines, and will save you about $130 if
you choose them. Callies Ultra rods are the choice for serious race engines.
Why 6.700 rods instead of longer ones?
We don't subscribe to the "longer is better" philosophy on rods. We
consider the piston ring seal to be far more important. The 6.700 rod allows
even the 4.250 stroker combo to keep the ring grooves intact. No oil
spacers guarantees good ring seal and no oil burners. Piston weight is still
quite light at 490-515 grams. Compression distance comes in at 1.330
Optional Items
- Steel crankshafts in 3.98, 4.125, 4.250 or 4.375 strokes
- Rod upgrades including ARP2000 bolts or Callies Ultra Billet rods.
- Virtually any custom piston size or compression

| How Big Is It? A .030 over 360 or 390 with a 4.250 crank is 445 cubic inches. Dish top pistons and 72cc Edelbrock heads gets 9.8:1 compression. Flat top pistons will net 11:1 compression. We've made nearly 550 HP with this combination! A .030 over 428 with 72cc heads and flat tops will get about 465 cubes and 11.2:1 compression. Going to the dish pistons takes the compression to a pump gas friendly 9.8:1 A 427 with a 4.250 bore and a 4.250 stroke ends up with 482 cubes. Flat tops are going to 12:1 for race gas, dish pistons will get 10.6:1. We have made over 780 HP with Blue Thunder heads on a 482 with 12:1 compression! Click for a complete displacement chart ! |
