I think I’ve entered into a deal for a fresh .030 over 454 with stock ported heads and an xr288hr cam
I know it sounds awesome and has decent throttle response , but I wonder if it has enough vacuum at idle for power brakes ?
Also , what stall converter would this need with a th 400 ?
I’ve had a 282hr comp cam in a 383 sbc and it was great but that car had a 4 spd
Had a performer rpm cam in a 403 that ran nice at speed but I had to keep the idle up around 900rpm for the brakes to work and it had a stupid TC that only stalled about 300 rpm over stock so was kind of doggy with the high geared rear
So my experience is pretty limited
The engine is complete except for carb ,
The current owner has 2nd gen camaro headers for it that he said he’ll include if they fit my 83 cutlass he also has an accessory drive and stock exhaust manifolds he’ll throw in
Would the stock manifolds be too restrictive to run in the short term till I saved enough for headers ?
What carb recommendation ?
Will camaro headers fit ? I think not ,but thought id ask you guys
Thank you in advance
Note : a cam swap is not out of the question as I want to have the engine gone through after I buy it
I’ve tried google searches but get inundated by sbc videos and articles
