help my future thinking

[fivespeedsteed]

so im trying to think out plans in my head for the far off future (crazy i know, it helps me make better decisions though). one day i hope to be auto-xing and open tracking with my car. so im wondering about the engine.

i know im gonna need a better cooling system, ect... im planning on afr 165's, nice trick flow intake mani, a 306, tremec trans, 24 lb. injectors, custom ground cam, custom springs... but im wondering. that should be in the ballpark of 350 hp somewhere with the bolt ons it needs. thats around the borderline how much a stock block can take, and because i want to open track, ect.... do i need to get something with thicker walls and a 4 bolt main? or can the blueprinted and .030 over stock block hold up?

flaming to a minimum here, im just trying to learn...

stock block can take what you throw at it.. get the upper valley girdle and you can take her as far as you want.. friend of mines 1100hp stock block, stock bottom end, GT40p heads and eddy intake w/100 something injectors and a anderson PMS unit.... 24psi on a 84mm turbo.. thats serious power.. i'd do that! I didnt believe it much at all.. but dyno numbers dont lie.. dear god they dont

what? are you kidding me? then how come i hear all this hubub about the stock 302 windsor motor block blowing after 400. cracking the block in a certain place.... whats all this i hear of 5/16" wall thickness when it should be 3/8"?2 bolt mains vs. 4 bolt?

he runs girdles in the valley that seriously strengthen the block.. before it happens, no one go BS'in me.. its not my car, its what i was told, and what i was showed.. time tickets are in the 9's quarter mile.. he daily drives this car btw.. laptop in the passenger seat. another guy has a GT in the 9's on 15 psi.. bone stock bottom end

a stock block can take alot more than 350 horse

and there is no definite point where a block will just break only because it has over a certain number.

the more power you make the greater chance you have of breaking the block

but IMO the stock block is alot TOUGHER than people make them out to be

it takes ALOT of power and HIGH rpm to rip up a block and with a street car, very possible to have LOTS of power but where are you going to be revving it up for a long time.

and by alot of power and high rpms i am talking 600+ HP and 8k plus rpms.

i wouldnt worry about your block. a 306 with afr 165s and a trickflow intake and a cam isnt really radical.
you have nothing to worry about.

Everything I have ever read said that 500hp is pretty much where stock blocks start to break. Me personally, I think using a stock 5.0 block on anything over 500hp is just asking for trouble.

4 turbo setups later, and street racing and drag racing alot.. this guy hasnt had a problem.. i'll get a vid ofit oneday.. he's going to help me TT my 92.. already have the turbos, they may look like peanut turbos, but together there plenty big enough for what im looking for.. TD05 16G's.. daytonas etc used em

 

[Foxfan88]

i'd worry more about a rod coming loose before the block breaking. if the block breaks theres more of a chance of saving the bottom end.

if a rod comes loose it will destroy everything or damn near everything.

those will spool up quick

those will spool up quick

ya buddy thats what im hoping for.. tiny turbos attached to the end of big ass longtubes equals a easy spool.. i'm looking at 12ish psi.. girdles, gt40p heads, gt40 intake.. all ported out.. my 2021 cam i have now.. finish some little things on it.. and maybe a damn 4 point cage just so i dont rip the car apart

 

[fivespeedsteed]

so my setup i mentioned will do just fine with a stock blueprinted to hell and back? even after beating on it all day at a track event or such?

whats the best way to make the rods secure? just a nice rotating assembly? are i beams or h's better?

this girdile your talking about is this the main support girdle?

all this stuff im doing would be under the stock rev limiter. until i get comfy with it i may mess with the powerband ect.
