ok so i have an idea. so if a 305 will rev more than a 350 w a stock tpi. soo if that same tpi was dropped on a 283 would revs be much higher? im talking a properly prepared 283 not a wreck out of an old impala. solid cam, afr195's or similar. see i plan on dropping a 283 in a datsun 240z, now keep in mind i have an iroc. but lets face it, a 283 wouldnt move a camaro. but in a package thats only 2300 now thats a different story.

 

The 283 is not going to rev to 8K with TPI. You might as well use a 305 and have some more torque since the 283 is not exactly a high HP engine either.

 

and as i figured someone was going to suggest going against the 283. besides thefact that it has better rod ratio, shorter stroke will apparently rev way higher with less piston speed. how about some suggestions simply related to a 283 and not recommending another block because im going to be stubborn, plus i hate 305's. so what would it take injection wise to peak at 8k, a hsr? theres no way im gonna go back in time to carbs, now that im starting to really understand injection. (got my nose in the how to tune and modify engine management systems for the third reading and finally starting to get it) i plan on using it on the road courses in oklahoma, goin there next month. my buddy w a 240z says a chevy will never beat him down the straights b/c i would have to shift due to lack of rpms, well im determined to at least not have a lack of rpms. so plz advize 8k rpm injected 283

 

i guess i should include what i have together so far. i have .030 kb .160 dome pistons, eagle h beam rods, factory forged, tuftrided crank(grey color). and a 62 block. thinkin of usin the the tfs aluminum street heads w 1.94 valves to clear the cylinders, prolly need some porting

 

You can turn 8k RPM with a 400 if you want. CI or stroke or rod ratio does not equal RPM.

A TPI intake will flow a fixed amount of air. So, regardless of how many RPM's you turn, your HP will be likewise limited. You will just be spinning the motor faster and risking more parts breakage getting to the same power level. If thats what you want to do, well thats up to you. I would not walk in thinking a 283 is magically going to make more HP with a TPI than a 350 would because its a 283. That is not going to happen.

 

well I have to agree with both of you, a 283 CAN produce power with the right equipment, but done wrong and your going to be spinning your engine high RPM and producing jack ****

 

TPI is not meant for high RPM use. Its not going to work for what you want. The 283 is not inherently a high rpm engine. Just tossing a big cam in is not going to be enough.

 

the recommended piston speed on the street is what, like 4000 fpm right? a 283 at 8 is at 4000. im not trying to argue that a motor will or will not, but doing it within acceptable limits. also figure in the smaller bearings. ok a tpi may be out of the question to pull 8k and still have power there. would a hsr come close?
