Id like your input/thoughts

I drove Rick’s T bucket with 500, did a hard launch it scared the shit out of me.

yeah Ive built enough street muscle car or performance engines for decades, to know whats required in almost any application,
to both prove a well designed engine combo, has impressive power without making the all too common mistake beginning builders seem all too inclined to make...
of trying to build a race engine and install it in a car thats to be used the majority of its life as hot street transportation,
theres a huge difference in how you select component designed too endlessly spin tires and scare the crap out of you on a car designed for impressive street performance,
and a true race car power plant thats designed to produce peak power over a rather narrow upper rpm range,
your race engine will have 50-100 more peak power, but its almost worthless in a car used for transportation,
in most cases its designed to provide power in the 5500 rpm and up rpm range and little or no concern is given to street-ability or long term durability,
and your well designed street transportation, engine is designed for brisk street performance, and a wide torque curve, it is hardly lacking in power.
it may not reach well above 6500 -7000 rpm but with proper parts selection and drive train gearing, it can scare the hell out of those guys who don't have the experience and skill to control it.
for some reason guys seem fixated on only peak power, numbers,
rather than instant torque and extended durability, and the fact you can,t begin too apply the power, and torque,
a properly designed street performance engine will have,
with street tires never seems to enter their thoughts.

Made a shakedown run Grumpy.
The 540 with the Crane Roller Cam makes stupid high horsepower.
678 HP @ 7,500 rpm.
In the DANGER ZONE.
The supplied Manley Chrome moly steel retainers have go.
Upgrade to Titanium 10 degree retainers.
Torque is not that impressive to me.
Pontiac 455 race cam race high compression race fuel fed does better....
But this is a real light car at 2400 lbs.
Killing low end torque and midrange and shifting up higher in power band will make the car easier to drive and control.

I want to review reults for a few minutes.
Save an will post soon.
 
9.3 :1 static compression does not seem like alot for modern aluminum heads Grumpy.
I will enter try it.
See what results are.
theres zero doubt raising the compression to about 11:1 would provide a great deal more power,
it would also most likey require high test gas while the engine as spec-ed should run on regular
and still provide a fun power range, youll rarely use more than 250-300 hp in a 2400 lb car even if you want to briskly accelerate before lack of traction becomes an issue,
you want a horse power curve, and acceleration curve that comes on like a rocket booster only after 3500 rpm, and above,
max off idle torque is counter productive, you want a very predictable power curve,
durability, and lack of and tuning issues is the goal, the engine as listed should easily produce well north of 550 -600 hp ,
and certainly with proper tweaking and tuning 650 hp is well in reach of that 540, bbc,
drive that car around town, short shifting at 3500 rpm,
and you get semi decent performance and mileage,
stick your foot to the floor and you best have a great deal of open highway free of traffic ahead of you,
because your going to be covering a great deal of pavement very quickly ,

and need to shift gears every few seconds,
and you better get used to long discussions with the local highway patrol,
guys who youll get to see frequently.
(even if its not particularly on your friends list of things to do today)

Kinda leary of the 1.50 :1 Rod to stroke ratio.
I know the Dart block is real strong.
Pontiac 455 stock has R/S ratio of 1.57:1.

93 octane 5.3l low boost very predictable lighter more nimble in a car designed for a road race application. No huge anchor BBC up front. Gas milage will trump the 87octane. Perform like stock car till on the boost. Can be done on budget cheap. Turbo forums guy do it all day. Tuning so common now a days. I stick with my choice over gigantic bbc.

I have fond memories of my Late Bud Bill's 572 BBC 1981 Corvette.
He disguised as a 502 BBC with factory cast valvecovers.
Started off as Marine backup Tug Boat Motor.
Sonny Bryant Billet Crankshaft hidden inside.
Titanium Valves.
Smith Bothers Titanium pushrods.
Much more.
Godspeed Fast.
It would twist the frame at high speeds.
To keep it going straight at 140 mph you had to counter steer gradual.
Full 1/4 turn of the steering wheel to compensate.
He did it so gracefull.
Everyone was scared to death riding with him.
I was the ONLY ONE NOT SCARED.
I LOVED IT.
No one can ever drive that Vette again but me.
I am the only person alive that knows how to.

I beat him with my 1970 TA RAIV 455 4 speed because I could hookup clean and fast.
Lighting fast shifts made by Me.
TA made brute power too but at less HP.
Hooked and booked I call it.
1/4 mile.
But he caught up and passed .
 
Yes agree Brian no replacement for displacement 1 bar on a turbo doubles an engines displacement. Why s475 s480 turbo combo 5.3l STOCK bottom end running 800+ torque and 650hp insanity controllable more efficient then NA. And staying together these are the slower street guys. The big boys do it to the BBC or pontiac run big boost. Stock LS 5.3 pushing 1000hp proven. Would I, never pushing luck at that point.
 
Want a fun cheap car buy a early 2000 audi a6 with 4.2T engine get one for less then 5k $500 chip and you have 500+hp awd

Bill was kinda like Grumpy.
More Radical like Me.
Wish you could have known him.

People said we were like Father & Son.
 
I like olds and poniac also I want to spoil up some weird engines one of these days mega squirt batch fire. Use stock turbo setups but double down. Use 2 k03 audi turbos on inline 6 would be fun combo.

You seen what those guys did to me on the Trans Am Forum.
So did Grumpy.

Grumpy is the only Old Timer we can Rely On 200 %.

I will be back with My TA.
I like the Chevy Guys.
Leaving them alone.

The Dyno simulation by me is skewed.
I did it at .050" cam lift events.
Crane listed at .004" seat to seat.
Just redid the simulation.
This 540 is even more powerful.
Way more.

Let me save.
Post it soon.
