Hi guys, I know it's been done to death but I'm after a cam recommendation, please.
I'm putting together a Gen 1 3883 SBC in the land down under, it's based on the Eagle stroker kit .....
+.060" flat top 2 valve relief speed pro hyper pistons (-5cc) and 5.7" rods.
Zero deck height, a .038" head gasket and 72cc chambers = 10.35:1 static compression.
Edelbrock performer air gap.
Edelbrock 800cfm vac. secondary carb (I believe Edelbrock rate their carbs differently so its equivalent to around a 725cfm holley).
1.5:1 roller rockers
Trick flow 23deg. 195cc cylinder heads 2.02/1.60 valves with advertised flow figures of:
196/135 @ .300"
234/167 @ .400"
249/186 @ .500"
249/199 @ .600"
I'm hoping for 400lbs/ft @ 2500 rpm, 475-500 lbs/ft @ 4000 rpm and between 450-500 hp @ 5500-6000 rpm.
The car is what I think you call a fleetside, we call it a utility vehicle or ute for short and I want it to be an all rounder.
It will see some light towing, a fair bit of highway use (our speed limit is around 60 mph) and the occasional Friday night at the dragstrip.
Above all I'm after good throttle response, it currently has a T400 with 2500 stall and 3.25 rear gear which I plan on keeping.
I read an article by Steve Duntech who dynoed a 383 similar to mine with a Lunati bootlegger retro fit hydraulic cam (224/236 - .554/.554 - 108) and it made 470lbs/[email protected]
rpm and [email protected]
rpm with Holley heads and 9.6:1 compression , so I'm hoping using 10.35:1 will put it in my ballpark.
Running the higher compression won't be an issue as we use 98 octane fuel here.
Any alternatives or other suggestions would be great.
Thanks guys ..... I really enjoy this forum.
In case you're wondering why I don't ask locally ..... I can and have ..... but I figure why not ask the folks who've built millions of the things ?????
OH ..... and please don't begin the replies with G'DAY MATE , we don't actually talk like that here ..... HA HA HA.
