for the 278ah from comp cams is it necessary to change pistons?.. is there a diff way other than build from the crank up?
278ah from comp cams
- Thread starter gt04pony_13
- Start date
They have to be notched to allow clearance
what other mods do you have? i think you would be happy with the 270s and you wouldnt have to do anything but put them in...and i believe they recomment at least a 3:55 in the rearend for those...
Correct!! Unless you have a lot of other mods or plan on pulling the motor for something just get the 270's.
Yes PTV is an issue with those cams.
shorty bbk headers bassani x pipe cats. and borla stingers on top ive got steeda pulleys accufab tb and plennum 70mm and a jlt ram 3.73s thats about it. ohh and diablo tuner.
270s or 262 the other guy said 262 r better??? this car is not my dd. shes for the weekend races. i just dont have enough for a kenne bell right now but im hoping to upgrade when i can.
278's ARE good race cams, but remember with your CURRENT set up:
You don't have enough exhaust
You don't have enough gear
You don't have enough head flow and intake also (to take advantage of)
Keep in mind that i AM talking about a weekend warrior. your mods are more in line with a street car. the only reason that i am saying this is those are big cams, bud. you will have to further upgrade everything i mentioned and more, to realize the potential of these. it becomes multiplied when you throw an automatic transmission into the mix ( i don't know what tranny you have )
Since you said that you plan to add a blower in the future, that will defenitely help with the compression side of things. even though i love Twin Screw blowers, with those cams, if it was my drag car, i would get a bad ass centrifical, up the compression even more and gear the hell out of it. :bowdown::bowdown:
yeah i do agree i wont do 278's but now im considering 270's or 262's keep in mind i will add a blower later in time
My bolt on 00 with those cams, valve springs, adj timing gears, accufab t/b - plenum, shorties,steel flywheel, centerforce, sct tune and 3.73's made 300 rwhp. Until the crank bearings spun. My pistons where notched while in the block. I have yet to start rebuilding it. This car was my dd also.
well IMO...i was looking into a blower...that is until trick flow came out with there new 2v aftermarket heads...im waiting to see info on paper but they are talking over 370 to the wheels with a set of their heads with comp 270s. these heads flow 240cfm. numbers like that are easily achivable with a blower...however numbers like that on an N/A 2v are great and something to be proud of. i would recommend looking into a heads/cams/intake combo. thats my plans...you will probably be putting down about the same numbers with a full bolt on car and that combo vs a blown 2v. all up to you...thought id throw my 2 cents in.
These new heads look to be the answer for 2V guys who want to get some respectable power N/A
But you can only get so much torque out of 281 ci.
Sooner or later, you WILL be craving more power and that's where FI comes in. besides, any upgrades you make while N/A will only benefit you later when you decide to get blown :beer:

Those heads are great.
cool i will consider those heads sounds pretty impressive. will these heads clear the 278's? i thought ive heard they will so u won have to notch the pistons??
