Default StreetSweeper HT open cutout Idle

Specs are 228/232 .614/.600 111 LSA. The sound level meter recorded max noise at 112 dB idling around 900 rpm. Still needs some tuning...

I have a Vigilante 4000 stall that takes 2500-3000 rpm to get up to speed. Its nice having the luxury of choosing noise levels at the touch of a button.

I considered the 236/240 SS, but I didnt want to have to flycut stock pistons if I went with milled heads in the future. I have stock 241 heads with .040 head gaskets. My goal was to build a quick street car without sacrificing drive ability.

So far, the loose stall had a bigger impact than the cam. Yeah the cam sounds rough and rowdy, but any rpm over 1500 feels as smooth as stock. I cant really say if the cam has added much power, I installed the torque converter a week before and it has been an adjustment just to get used that.

Thanks for the info, I really just want a nice lope, I have enough power for the street now. You get on it anywhere but the highway and you can barely get out of first.

I went through New Era, they shipped fast out of NY and they had great customer service responding to all my questions. The cam is a little pricey by itself, but they had good prices on a walbro 255, hotwire kit, and chromoly PRs so it made up the difference for me. I went with PRC dual valve springs from TSP. In retrospect, it probably would have been a little cheaper to buy everything as a kit, but I pieced everything together over some time.

112 dB through the open cutout. Its around 75-80 dB through the catback.

Just for comparison, I recorded 96 dB through the open cutout with boltons and the stock cam.
