Need Advise/ Cam, Heads Etc.

[Savage Sierra]

Anybody who has read my post recently knows I am planning to a top end and cam change on my 95 5.7 TBI.

I had my list ready to go which included a set of heads, cam - lifters, intake and a custom dyno tune.

Unfortunatly some unexpected medicals bills presented them selves this month.

I can no longer afford the heads. But I have purchased Comp Cams CCA-K12-268-4 cam, lifters, springs and timming set, a Holley 300-66 Projection TBI intake w/2" throttle bores and a set of three underdrive pulley's.

My question is: this cam and intake set up will yield around 5500-5800 rpm, do you think the stock swirl port heads will be adaquit with the new high lift springs, untill I can afford better heads?

Oh yeah, I also plan to install 1.6 PRW roller tip elongated rockers arms.

Has any one ever flow tested the stock swirl port heads? I heard they flow around 185cc....?

I just built the same thing 95 5.7 on my tahoe,thats a 474 lift on the cam right??? well she runs real well but I still need a tune cant find the time to get to the dyno,I kept the stock heads and had em worked by a reputable(I hope its right)machinists who builds race engines for a living (30+yrs)I'm looking for torque being a 4x4..but I need a tune bad to get all it has out of it....I think you'll be happy with it,I'm with mine but need to tune it....Pete

Did your Engine guy remove the swirl port intake ramp?

no he left them in and improved the flow of the heads it saved me over a grand instead new heads I'm not really looking for top end though it's all about torque for me bro d/d and I drive all over for work never know where I'm going until last minute....Pete
