no more SMALL small blocks??????

[89IROC&RS]

this is annoying, apparently the aftermarket has decided that no one can make sub 350cid small blocks anymore. with the exception of a handfull who still sell 327 cranks. Chevy has had cranks with 3.00in and 3.10in strokes, but there isnt one available anymore, unless you want to buy a "rare find" that is in questionable condition. im just annoyed by this, cuz i am trying to build a 302cid V8, and its looking like ill need to get a custom billit for $2400.oo or a Lunati pro race crank for $1400.oo when a 4.00in stroker crank sells for $350.oo on ebay. for some reason this is backwards to me, but its damn frustrating. just had to vent.

i hear ya buddy, guess anything under a 350 just aint race worthy enough...

[89IROC&RS]

you dissin my 302?

[Chevyracincamaro]

naw, im dissin the market...

[DaMoNe6969]

them 302's were kick ass engines!

[NailZ69]

wasnt the 302 the ford eng?

[89IROC&RS]

ok, those little "..." things confuse me, i never know what they mean.

yeah and hows 380hp and 380lbsft out of my little 302, with unmodified L31 Vortec heads and a 10.5:1 compression and no power adders with full race prep and porting and an accell superram plenium and runners, im estamating 450/450 power numbers. and with the vortecs the powerband isnt even going to be as "peaky" as you would expect from a engine this size. granted its high up in the powerband, peak power is at around 6k, and torque tops out at around 4500, but i should be above 360lbsft from 2500rpms - 6000rpms.

302 was in the camaros alone from 1967 to 1969. It was a 350 block and a 283 crank, for a 4in bore and 3in stroke making 302cid. This was due to the size limit in SCCA trans am racing at the time of 305cid. it was rated at around 290hp, but really made more like 350hp, and in race form, made over 450hp. the thing wound up to 8k and pulled like a hemi in the top end according to magazine testing of the time. however it was not a good street engine, with a solid lifter cam, 12.5:1 compression, and large valves, it was slightly aneimic in the bottom end where most people drove it on the road. it was kinda the S2000 of its day, you really had to wind it up to make it come alive. but the 1967-1969 Z28s were basicly just street legal race cars.

those are the reasons i want to build it.....

A. no one knows anymore that it was a chevy engine, and bad ass, so when people ask why i have a ford engine in my camaro cuz of the 302 badges, i can spread the word.

B. its the only engine that was put in the camaro exclusivly, not even the firebird got it, no other GM vehicle got a 302, so its camaro specific. and only to the Z28, Which is what im putting it in, just 20 years later.

C. They are bad ass engines, with modern parts they can be even better than they used to be. which is what im doing, taking a classic, and modernizing it.

if you are only going to be spinning to 6k, you are defeating the purpose of the short stroke. The reason the 302's of the day were made to spin those High RPM's ws to take advantage of the short stroke's rpm potential and make more power. Build it to make 7500 rpm's, then you will smile.

BTW, my dad has a 302 in his 68 camaro.

Don't diss the market, don't diss the engine, Diss your fellow SBC owners/lovers. The market will make whatever there is demand for. IT is your people's who have deemed a SBC under 350 unworthy.

[89IROC&RS]

GTstang, i know i know, but i dont have to like it

oh and deadcarny, who said i was only takin it to 6k??? thats just the power peak, ill probly be shiftin at around 7 or 8k. trust me its being designed to rev. im using just about every trick in the book i know of.

[Deadcarny]

If you peak around 6k, you really do not want to hold out to 7 or 8k to shift, it will slow you down. you really want to shift just after you peak so you can stay in the powercurve throughout your run. If you are running on road course, you want the car to handle the high revs for a sustained time and want your power where you plan to spend most of your RPM time.

[89IROC&RS]

well the 6k power peak is before the superram intake which is supposed to raise the rpm band to around 6500rpm on a otherwise stock engine, so peak power on mine may be between 7k and 8k im just playing with numbers on desktop dyno 2000, so obviously id have to build it and really test it before i decide my shift points.

ever think of doing the LT1 Intake Conversion?

The Popular Hot Rodding write-up on that page was done By my friend tom in the Shop down the road. the shop belonged to somebody that USED TO BE a friend of mine till he stabbed me in the back..LOL...That is how I learned all about what mods truly work and what to expect form them in terms of a power gain.
