what to do with the motor after the season

[camaroracer1992]

after the race season im thinking of a few options. here are the ones im thinking.

1. keep my 355 and go a slightly larger cam, which at that time would be a roller cam

2. bore and stroke the 355 out to say a 427 with slightly higher comp and bigger cam

3. ram jet 502

4. sell all my small block stuff, and 700r4 race prepped trans and put a big block in it from shafiroff and a reverse manual th400 the one im looking at is here http://www.shafiroff.com/ultrastreet/540_675_engine.asp

i want to do this cause frankly the 355 isnt much fun and id liek to be running 10 flats or high 9's on motor alone.

get the mountain motor and lay the smack down on everyone!

I'm partial to a big small block. Easier to get a car to hook without so much weight on the front end.

Just remember Joe,the jump from mid 10's to single digits is an expensive one. I know first hand. LOL Lot's of broken parts and money spent on safety equiptment. At least you can learn from my mistakes.

YOU CANT GET THEIR WITH A STOCK 4 BOLT 355 BLOCK ?????? YOU NEED A TALL DECK ( BO TYE TYPE ) STROKER CLEARENCED AND A BIG HAND FULL OF CASH OUR 79 CAMARO WITH A 355 ON RACE GAS 2 SPEED BACKHALFED CAR RUNS 10;30S 130 MPH ALL ON MOTOR NO ADDDERS JZ

john i have a dart little m block, it can be bored out and stroked much further then a stock 355

[Tru2Chevy]

Big-inch small block FTW!

Big blocks weigh too much Joe....

[camaroracer1992]

looks like a big inch small blockl ill have to start planning/talk to engine builders since mines out of businessif i go that route, ill be getting rid of my th700 and going with a th400 with a transbrake

[Ian]

acutally, I want to change my vote for big inch small block. I just remembered the big block vs small block race between an early second gen (small block) and a second gen nova (big block). small block won it.

I have built and raced both small and large the bigger a little motor becomes the more heat becomes a problem unless its on alky a large BBC with alloy heads and 9-1/2 to one will run on pump fuel well some times these days and will make up the difference in weight / power --- a special fuel large small block is a pain to control with heat and detonation / verses the power you get they need much more in the way of oil clearence rings rods and mains and a special anti cavation ( anti spark oil pump ) that limits your cam choices YET i have seen many 800-HP and more SBC motors some last and than theirs the others their is no Substitute for cubic inches the bigger the engine the less effort to go the same as a small real high effort combo its all in the numbers ( MATH ) my 2 cents for what its worth jz

why stop at 427? theres a stroker kit that will get u 454ci

[Brando56894]

stroke that som bitch!

The head gasket gets real thin between bores on a 454 small block. I would not go that big on a motor that will see nitrous unless you like changing head gaskets. Also if you run a 4" stroke with a 6" rod the compression height is only 1". You then end up with a thin top ring land. Not much margin for error. I know this from expierience. The gain from the few extra inches would not be that big anyway.

i say leave the motor and figure out why that turd doesn't leave harder. have you even made a pass on both stages yet?

[camaroracer1992]

the turd leaves hard on the nitrous!! 10.7@125 with a 1.4 60 time, i think my convertor doesnt stall high enough. i know on motor it doesnt launch hard so in turn this is affecting the nitrous launches to. im wondering if a th400 with a transbrake and a slightly higher stall with a roller cam would be good or not??

[NJSPEEDER]

leave teh TC and cam, transbrakes are always a good idea, and time the second stage to come in at 1.5-1.6seconds. that should get you out of the hole at the limit and bring the second hit on as soon as you grab second gear

and if you want a trans to put a brake in i have access to a few powerglides

A nutter vote for a big small block here!

[jrsfast84]

Now, my 2 cents, if you still want to run pump gas, 434"-(4.155 bore,4" stroke,6"rod), 10.5 comp., big cam(nitrous roller), good flowing heads, th400, and it depends on the weight of car, at 3100lbs, mid. to low 10's,on motor, plus i don't know how much NOS you have, but there's always little speed secrets when building a motor. JR1.


Right now, I'm putting my 440"sbc back together, and hopefully be getting to Island on a Friday night to make some passes in two weeks mybe the 30th., cars painted and back together and only have little time before Maple Groves - NMCA's Fastest Street Cars in August 25,26,27th, hopefully i can get the car to go DOWN the track instead of UP!!!!. i changed alot of rear suspension parts.see you's on a friday. JR1.

[camaroracer1992]

yes jrs id like to still have a pump gas motor
