So, what, a 292? Then it needs more. More rear gear, more compression, more cam (30/30 solid), more cyl head (camel humps 2.02), and a Holley 3310.

2.02 camel humps don't work good on small bore because cyl. Shrouds the valve.. I'm running power pack pyramid heads with small valves, edelbrock performer intake with quadrajet. I'm running over 130 mph now.. Last pull I shifted in to high at 6,000rpm... I got all the power I need.. Widow maker...

Love the 283, I have the 283 with power pack heads as well, they are great for compression but don't flow great.
However they are the cats ass on a 283 and can be worked out to flow decent enough.
I think they can be worked with 194, 150 valves as well.
I am planning the 3030 duntov solid cam for it though.
My last 283 was a screamer I had the 151 cam in it and it seen 7000 RPM on more than 1 occasion, and it got their in a hartbeat.

I don't know what cam is in engine but I know it's a screamer... I'm running 3795896 heads 1.72in. 1.5ex. 60cc chamber..

Yup... Still pulling... I like to live... 55 be plenty for me.
That 283 is bored to a 292. 3 15/16 bore. The Z28 302 had a 4" bore, that is a 1/16" bigger bore, so just .030 per side of bore. The stock Z28 came with 2.02 valves. The 302 I raced had 2.08 intakes in it. So yea a set of double hump heads would add to it, but for what they sell for now, you can buy a decent set of new aluminum heads.

I have done allot of research in this, and if you bore out to the 4" (some 283's can do) for a 301/302 you can go up to the camel humps or a set of aluminum aftermarkets with the 202 valves.
But a 283 with only a small bore the valve will hit the cylinder wall with a medium sized cam like the 30 30. at 485 lift.
You might be ok with the 151 cam, its under the 450 lift threshold.
Also if you want to go with a bigger flowing head you have to get the CC's down to 60 to keep the compression up witch in a camel hump means allot of machine work.
Love the 301, that's my plan B if I can get a set of pistons that don't cost me limbs.

I think its the perfect engine for a bucket.
People say its low on torque and it doesn't make any power bla..bla.
Ok that may be true for your 10 ton boat of a 1960's car, but put it a 1800 LB road legal rail car where you don't need the torque of a 454, piston speed is king and look out for shifts at 7500 RPM .. lol
I have seen them rev up and down so fast that a regular of the shelf tach can't keep up.

Ah... humm ... well geez ... is this in the T ? I mean really ... didn't take you long ... that fast ...
DOES MOMMA KNOW 'BOUT THIS ?????

And yes sixty five FI heads will work. Out of youthful inexperience I went out and bought a set from the local Chevrolet dealer ship, kept them under my bed until I saved up for the rest of the motor (265 out to 283) didn't check piston to cylinder wall clearance, biggest Erson flat tappet cam they said would fit, put it together and a week later off to Texas for a year. Ran like a top. Did I mention it was the 265 block without an oil filter adapter. And yes I changed the oil kinda regularly. Kinda.
Ahhhhhh ...... youth, indestructible.
Too much science, not enough cam.

I'm running a 1958 block... With Oil filter adapter... It's all the power I need... Like a say, if I can put around at 55 all day long I'm good...I'll tell ya this there ain't no corvair 4 carb GT that wants any... And a hellcat is nothing but a pussycat....ever get tunnel vision in a car...
