Time for more power

pushrods that came in were a little to short. Decided to order .050 longer and while I'm waiting, port matching rhe adapters to the heads and the intake to the adapters.
if this intake and head combination picks me up 50 rwhp, it will probably stay a while. 600rwhp and an automatic transmission high stall will get me off in the 9s and a roll bar will come before more power will.

That’s a strong 427! Do you think dual exhaust is needed on a 383? I’ve been eying the same system you have on your car, but idk how much it’ll be worth over a 3inch Y pipe with Loudmouth..

Btr intake and adapters dont fit in an fbody. It hits the cowl and pushes body up before it touches the kmember by a quarter inch or so.
msd ordered, unported at first to see what my powerband looks like. I'll port later but I'm trying to be ready for cruising the coast weekend
edit: had intake ported since I had time while out on the boat. Motor went in yesterday, still have to get the exhaust welded up where I come vbands on headers.
hopefully this evening I'll have it all done and ready to crank.

I cranked the car with new heads,intake set up but had a fuel leak on back of the fuel rails. Only let it run for 10 seconds. Had to let the fumes out of my shop and was coming back to my job for a week the next morning so left as is.
have new fuel line kit to change the line and fittings on back of rails . Will do that when I get home Tuesday, then get it ready for the dyno that Friday October 16th. Track event the next day.
things changed since last run of 10.29 at 133 with a 1.44 60ft
heads from sps ported 823 castings with 66.5cc chambers to Mast Black label LME port ls7 heads with 60cc chambers [11.59-12.5=1full point jump]
rocker Arms from 1.7 ratio yella terra to 1.8 crower
(cam going up from. 689/.672 lift to .730/.712 )
intake from the short runner BTR to a ported MSD longer runner.
Brakes. From stock front brakes that were dragging to strange pro 2 kit that has no drag.
Previous dyno with btr intake ,3" speed engineering true duals and 2" tsp headers through an 8" converter 4l80 transmission and 4.10 gear set was 543rwhp.
will use same tires and try to keep it as fair as possible to see what it gains but main thing is what it does the Saturday at the track.
