6776h cam selection

[BadAssGN]

Looking for suggestions for a Flat tappet cam that will work well with this turbo

I know Roller is the way to go so save it... it's not an option for this customer.

so here is the Critical parts list

6776H cover 4" 3 out

Gbody stock location intercooler (thats right, it was a bittch to install)

60s with TT alky chip

Razor kit.

ls1 maf and Trans plus

3200 stall

.030 109 block

3 billet caps, studs throughout

Ported big valve heads

ported intake

70mm throttle body


Just looking for what cam is going to have the best street manors and pack a big punch with this combo

TIA

p.s. this is not for the car in my SIG

Why is a roller not an option? Everything else is there so why not put the iceing on the cake. A roller would compliment that combo so well. My 206 roller sure woke my turbo(6776bb) up big time.

Just asking.....

okay.

The guy wants this (his backup engine) built. still fairly stout with studs and main caps etc. he does not want to put $1k into the Valve train of this engine because he wants to build a forged monster in the next off season.

he does a bit of Street racing (very sucessful also) but currently has a Bone stock engine.

I guess right now it's plain and simply not in the budget for this engine.

the next engine will also see a Convertor change so we can use a bigger cam..

I know there are some new grinds out there but with the Tight convertor I'm looking for feedback so I don't create a mismatch.

I had a 3200 converter and I actually just got it back from PTC restalled to a 2800. I was blowing thru it at 3200. It was on the loose side though. I will be installing the 2800 10" this weekend. These big turbos spool so easy and make so much power you dont need as much converter. Of course this is just my application. Every car is different and I dont want to get into a converter/turbo "whats best" war thread here.

Only my track results will dictate if my decision(and Dusty's ) was correct in the restall.

I guess what I am trying to say is that my 206 roller/6776bb dictates a 3200 stall but I had to go tighter than the norm.

Lots of variables dictate what stall.. the small cam is one, turbo exhaust housing. compressor cover.....

The bigger cams get stall sensitive also.

Dls

DLS Engine has a nice selection of cams. Dan will get you in the right direction. Another resource would be Hartline Performance, Cottons Performance, or Weber Racing.

I had a cam wipe out at 5,000 miles. Going to a roller(210-215 comp with 1.55 t&ds) with new rebuild. I would not chance it again with a flat tappet.

I'm well aware of the issues of flat tappet cams, There are ways to make them live. proper break in, the right valve srings, EOS and regular oil changes are good ways.

I'm I the only one who has never wiped a cam lobe?


if yours wiped at 5000k then there was an issue.

Wiping lobes is a whole other topic

I Thought 212/ 212/ Flat Was A Good Cam. Dnt Forget To Have It Cryoed, I Heard It Really Helps
