trick flow 23* for 305
So i posted about this in the tech/general engine forum but i kinda figure i might get some more answers here.
I want these heads
http://store.summitracing.com/partde...0&autoview=sku
for the 305 but only because i think they'll b awesome for my 406 build someday. I just want somtin that is gonna wake up my 305 and then transfer and work better on the 406 someday when ive got the money to finish it.
I think the valves will work as long as i stick with a lower lift cam, the intake runners concern me tho. Since they're 195cc is that gonna cause problems for the baby motor since i kno theyre perfect for the big motor.
Any input is great thanks.

Re: trick flow 23* for 305
yea i shoulda mentioned ill probably be goin carb. i started gettin in2 that tuning stuff but i think id rather play with a carb. ive got the datalogging stuff but none of the burning stuff.
as for the heads im probably gonna get em as long as somebody doesnt say the 195cc intake runners are gonna mess stuff up. probably get the .600 lift ones too just to be on the safe side even tho i wont go near that far in lift ill have sum more rpm range.
as for the cam probably look for somtin around 230-240 dur and .500 lift 108-110 lsa

Re: trick flow 23* for 305
I'm pretty sure 2.02 valves won't clear a 305 bore..if they do, it's REALLY tight and you have no margin for error.
For that 230-240 dur. cam, I hope you're not saying you'll use that in the the 305!! With that much cam, and those big runners, the 305 will be a dog.

Re: trick flow 23* for 305
yeah the valve size is large for a 305 but it will work. the bore size will kinda hurt flow on the heads for the 305. bore isnt taking advantage of the chamber size and valve size
195 cc is very large for a 305 tho, it will suffer lowend torque loss. how much? i dont know, but i'd get a 2800 stall converter in that trans if you dont have something in there already. If the airstream retains high velocity thru that large port then you may still be alright. But seeing big ports and valves on motors not build right to handle them, you do see a lack of low speed power
I'd definately throw a somewhat mild cam in there to help boost power. Definately could use it
And your compression ratio will drop alot since TFS heads are 64cc and 305's are 58. Not a great match so you cant go big onthe cam else you will lose even more power
i really wouldnt install those heads on the current 305 at this time. If you want to get them do so, but wait for the 406 build. I think its a waste of a good head on a 305.

Re: trick flow 23* for 305
yea i was lookin at the ones that dont have the cnc machineing done on them so the combustion chambers are 62 instead of 64 cc's and with a thin gasket i should be able to stay in the low 9's compression wise.
mayb ill just wait till the 406... just didnt have the time or money to do it the right way, right now. theyd b perfect for the 406 tho right?

Re: trick flow 23* for 305
yeah for the 406 they wouldnt be a bad choice at all, depending on how wild you are going. i'd rather have the cnc chambers tho as they tend to flow abit better but its another 300 bucks i think... for that price you might as well get AFR's which flow better anyway
You can go ahead and run it on the 305 just dont expect it to be powerful low end will be gone, but with a somewhat medium cam, once you get that car revved up it should scream up top, not unlike the old dz302 race cars. no power down low till about 4000 rpms after that they move out ok.
i'd be curious how that car would act with a lt4 hotcam and those heads with a good carb/intake and tune

Re: trick flow 23* for 305
yea i was really wantin to use em on the 406 but i just thought i could throw em on the 305 and have a lil fun till i get the money 2 put em on the 406. if its gonna kill it tho then i probably wont... but if nobody's done it guess it wouldnt hurt to try... if worse comes to worse stick the old heads back on under the new intake/carb combo nd cam and ittl still run better.

Re: trick flow 23* for 305
yeah thats a possibility. I personally dont know what to expect out of that combo. I normally would suggest a 180cc head like trickflow's 175cc head or AFR's 180's for a 305 if you must build a 305. Those are the heads i want ot run when i build a 305 someday
But combine a cam like a lt4 hotcam under there and we may be surprised at how wel this car runs. If your willing to go thru with it, by all means go for it and post up the results after you get it tuned up and running good. you will need a torque converter tho, i cant imagine a cammed head car runnin well on stock stall speed
Even a 2000-2200 s10 stall would work better than stock if you do it on the cheap

Re: trick flow 23* for 305
who knows i might discover some crazy awesome combo and pull like 500 horse outa that 305... but probably not... im plannin on doin some dyno runs before summer so i can have some baselines and if i do it ill definately post about it after i run it again.
ive been looking at a hughes 2500 stall with the lockup, which reminds me of somtin else... since it wont b computer controlled anymore can i use the lockup idea on the tech page for like $3 or do i have to buy an actual kit like from painless? (just curious if you'd happen 2 know)

Re: trick flow 23* for 305
Make sure steam holes are the same on these heads. I've heard that 350 and 305 are different from each other, I haven't checked to see if it's true or not,but I would make sure so you can do the transfer as you said.

Re: trick flow 23* for 305
neither the 305 or the 350 have steam holes. only the 400 blocks do. 350 heads work on 305's and 305 heads work on 350's.

Re: trick flow 23* for 305
I didnt do anything... i just finally came to terms that doing anything to the 305 was polishing a turd... I still have the 400 block i might build someday but actually i defected and bought an LS1 and cammed it. Pretty easy 480-500 crank horsepower... haha

No need to apologize. I still think of getting those heads, though, and putting them on a ZZ4 or L31 short block with a 50mm TBI setup on top. Seems like a combination that would make lots of nice low-end torque for city cruising.

Re: trick flow 23* for 305
this is the older trick flow Heads (200) beating out the AFR 210
http://instructor.mstc.edu/instructo...sbc%20200+.htm
they stopped making the older twisted heads and jumped into the ford head mania.. sell more heads that way.
has ever body and there Dog makes a small block chevy head.
and nobody wanted to play with the push rod game.. (it was easy)guys
mine ran fantastic.. going on the new eng soon

they will work if you use a cam with .450" or less lift....go the duration route
