355 build plans comments welcomed
ok so here is everything that is going into my new motor and would like to know what those who have more experience then myself think about it. Basic goal is to have a fun reliable daily driver.
355 1pc rear main internally balanced eagle rotating assembly cast steel crank, forged I-beam rods and kb-7 flat top piston 10.3:1 cr
AFR 195 heads cnc ported 58cc
Edelbrock hi flo lower intake that's been ported, asm runners, ported and smoothed plum and 58mm bbk throttle body. 30lb injector with afrp
comp cam xr276hr with 1.6 comp gold self aligning rockers.
Car will be running a built t56 with 3.73 rear gears.
for tuning Im looking towards the dynamic efi P4 as Im running a 7730 ecm.
What have i forgotten to include in the build and what problems will i have with tuning?

Re: 355 build plans comments welcomed
Tuning may be a little tricky as that is not an overly computer friendly cam. Also, I'm wondering about your CR. Mine is 9.9 to 1 w/56CC Trickflow 175's but I have 13cc dished pistons. What size injectors do you plan on using?

Im going to be running 30lb/hrs Bosch III injectors.
The 7cc Keith black flat tops and 58cc afr heads putting me at 10.28:1 to be exact on the cr
What is a more computer friendly hydraulic roller cam that will still give me good power and be easier to tune?

That is the computer friendly version of your original choice.

Re: 355 build plans comments welcomed
thanks watajob. the only difference i could see is the lsa, the higher lsa 112-114 are where I need to looking for tunability reasons correct?
What about lifters? Should i just get a set of comp hydraulic rollers or is there a better design i can run. thanks again

Since the party is all over at 5K or so RPM, a quality OE replacement will suffice, IMHO. I'm using Delphi's.

Re: 355 build plans comments welcomed
so after researching everything I think ill be ordering this cam http://m.summitracing.com/parts/cca-08-466-8
please everyone Im really looking for input here on experience with this cam or concerns that i have not considered about this cam.
With an lsa of 113 and it being computer compatible it should be fairly easy to tune????
