Edelbrock top end kit
What do you guys think of using Edelbrock's SBC 435hp top end kit for a marine engine build? I am new to engine building and am having trouble finding books on marine engines.
The cam is a "Performer RPM Hydraulic roller cam".
"These cams feature more aggressive profiles than conventional cams without excessive valve overlap and are used in our 435 hp & 440 hp E-Tec crate
engines as well as the 460 hp Signature Series 383 crate engine. Roller tappets reduce friction, virtually eliminate break-in problems, and permit higher
valve velocities for increased performance. Intended for use with OEM or Edelbrock hydraulic roller tappets."
2204* 296° 300° 234° 238° .359 .365 .539 .548 10° BTDC 44° ABDC 56° BBDC 2° ATDC 112° 107°
Here is the link to the cam specs

Here is a listing of the parts in the kit:
2204 Performer RPM Hydraulic Roller Cam for Late-Model Blocks
60979 (2) E-Tec 170 Cylinder Heads, complete
6997 Timing Cover Gasket and Seal Set
7367 Cylinder Head Gasket Set for E-Tec Heads
7516 RPM Air-Gap Vortec intake manifold
8516 Intake Manifold Bolt Kit for E-Tec heads
8550 Cylinder Head Bolt Set

you don't want to use any of the RPM Edelbrock stuff for a marine application. You'll be better off using the Performer Edlebrock products. RPM is a single plane manifold and makes good HP in the higher RPM range but lacks the low end torque that a dual plane will give you at the lower end of the RPM range. Look for something that makes power from 1500-5500 RPM's. Remember, a boat motor is like a car motor towing something uphill all the time.

rpm intake I do believe is a dual plane just alittle dif from the perfomer intake. oh run stainless marine manifolds for no water reversion I run dry set up 670hp had the s/m since 1995 and I run in saltwater, go to trick marine for s/m. art

RMP is a high rise duel plane intake.
