how much HP my engine will have???

first i apologize for my poor english.
i have a 1979 pontiac parisienne 2 door with a v8- 305

here is the list of improvement for the engine,
remove catalityc thing
turbo muffler
manifold edelbrock #3701
carb edel #1400
camshaft edel #2102
timming chain edel #7800
and since it very old and lot of parts are tire those will be change too.

radiator
water pump
gaz pump
oil pump
valve spring and lifter edelbrock #5902
valve lock and spring retainer
new fuel and trans line.
and all the rubber tubbing.

no HP with those but just to be sure nothing break when i will be drag racing with it.


a few thing have been done yet, most will be done this spring. i already got most of the parts. waiting is terrible !

Why go thru all this time and expense when you could just buy a crate motor and decide what horsepower rating you want.

Edlebrock has nice 350 crates or just go to GM direct and choose one.

You seem to have the right idea for the top half of the motor but what about the bottom half ??? crank, pistons, rings.

Drag racing a tired motor will get you to a crate motor sooner than later.

i agree.. and a 305 isnt the BEST way to go.. about the most HP i've seen out of a 305 w/no NOS or anything is 380... and that is with everything new but the block.. lol plus alot of 305 and 350 parts are interchangeable... so they cost about the SAME price.. why spend the same amount of money on a motor that will give you a little more than HALF the power.. theres no replacement for displacement... bigger cylinders=more power.. boring does SQUAT as far as power goes.. unless you are building a stroker. then im not sure it does that much really... just go to a junkyard.. tell them you want a 350 longblock.. price should be less than 200 bucks... i bought mine for $125... good luck! by the way.. im not trying to discourage you on a 305 build.. it just would be alot more efficient to build a 350... your choice though.

the inside of the engine must be in exellent shape cauz he has own by a grand father before me, only have 100000 kilometer and running like a new one. SO i am not worry about that.
and $ limits the amount of thing i can do.

and i keep my 305 cauz i got 2 parisienne. the second one is use for parts only so if i blow my engine i got another one free
when i will get more money i will add a nitro kits.

and think about that, they use the same part in many engine like the connecting rod in 350 and 305 right? so the rod in the 305
"work" less cauz the 305 is less powerfull. the engine will last longer, and since i will drive a lot on road it's important. but i am just a noob... i may be wrong on that.

so do you have a idea of how much HP i will get out of it?

Provide us with the specs on the cam, what particular intake, and as much other info as you can. Not part numbers, actual specs .

If you are going to be building or racing motors, read up first. Its not a cheap hobby by any means. If you cant afford or dont have the knowledge to put back together/fix a blown motor, you dont have the money/skills to be racing it.

I mean that in a nice way.
