my main question here to everyone who reads it is... will this combo work well together and have no problems. if anyone has any suggestions please put your input. i want this car to run low 13's to high 12's. the car to start with is a 87 formula 350 origonal 700r4, and 9bolt posi with 3:27's
the 350 got a bad water pump and the stupid lady kept driving it which resulted in toasted head gaskets. im going to rebuild the whole motor. here is the platform.
87 tpi 350
BLOCK: tear engine down to bare block, speed pro engine rebuild kit which consists of speed pro flat top (with 4 valve reliefs) forged pistons 9:70-1 comp, speedpro rings, main, rod and cam bearings, complete gasket set, brass freeze plugs and high vol oil pump, magnuflux block, bore .030 over, polish stock rods, clean up crankshaft, edelbrock performer timing chain, crane compucam 2050 cam and lifters,
HEADS: stock l98 heads ported and polished, manley 1.94 intake and 1.50 exhaust valves, new valve seals and seats, crane pushrods, crane pushrod guides, comp cams valve springs and retainers, comp cams 1.5 aluminum roller rockers
INDUCTION: stock ported lower intake, either stock ported or slp ported intake runners, stock ported intake plentum, stock tb with jet airfoil, jet 160* thermo, jet fan switch, bbk afpr set at 48 lbs, stock 22lb injectors
IGNITION: accel cap, rotor, super coil, 8.8mm spiral core wires, rapid fire plugs
EXHAUST: edelbrock headers with 3" y pipe, 3" in place of cat, hooker aerochamber catback

Im hopping to get low 13's to high 12's with this combo

 

I think your combo will work together fine, however I do not beleive you will see the 1/4 mile times you want. Will you have any suspension work done, how about the tranmission?

 

well as of right now the drive train is all stock. stock 700r4 with 117,000 mi and stock 9 bolt with posi, disk brakes and 3:27 gears. the only suspension mod i have to do right now is lakewood lower control arms. what would this combo net me in the 1/4? (the motor listed above) and the drive train just listed? i do plan on some suspension and trany tweeks in the future and nittos out back

 

I'd say your combo wont get you your 12's or low 13's. More then like mid 14's

 

I think the key will be the "ported and polished" stock l98 heads. Depends on the final flow numbers. In my opinion I think 9.7:1 is a little high for pump gasoline and iron heads. Myself I would not go over 9.5:1. I'am not familiar with the numbers on the Crane cam. Allen

 

It would be nice to know what the cam specs are to really give a good estimate. But with that setup, no tranny work, or suspension work, I would say low 14's. The time in my signature, 14.39, was accomplished with the mods in my sig...not the ones that are waiting to be installed, but the first paragraph of mods. With a little traction, and some lca's, sfc's, etc, I could have hit a 13.99. With a good torque converter on top of that again I would have hit mid to high 13's. So judge yourself according to my experience if you like. My times where accomplished at sea level, with mid 80's temps.

 

GM raised the compression on the iron headed L98 in the 1991 and 1992 cars to 9.75 to 1. It'll work.


Mine ran 13.58 with a stock L98 and 3.73 gears, 2200 converter, and drag radials. I had a 1.81 60ft that day too.

 

I think he can get into the 13's. On my car I get 8.9 and consitent 9.05's thats on the 1/8th mile, so that'll be like low 14's. The only thing I've dont is the whole exhaust system. And I got a 92 GTA l98 engine.

i was origionally gonna just tear down the top end and put head gaskets on it but its going in for some minor touch ups on the paint so just gonna pull the whole engine and rebuild it. the cam specs for the crane compucam 2050 that im gonna put into it is 272,284* and .454intake and .480 exhaust lift with 1.5 rocker arms. im gonna run compcams 1.5 rollers so that will be the lift.reason i wanted to go with the 9:70-1 comp pistons is i can get the whole rebuild kit (look above for what kit contains) for $429.95 and it comes with speed pro forged flat tops. i most likely wont get into more suspension mods until mid summer. what most of u are saying is that it is a good combo that will hit me low 13's but i gotta do some trany and suspension tweeks? if no trany or suspension tweeksand all motor more likely low 14's high 13's

 

I'd say get some gear in it, some stall 2200 s10/corvette convertors are pretty cheap and some sticky tires(biggest gain). I'd just get some used bfg D/Rs and run them on some old rims at the track. Get a cutout too, it will help and is a cheap alternative to an expensive catback. Port the crap outa that intake manifold. I'd say if you do all these things plus your other mods low to mid 13s should be relatively easy. You should get some chips burnt to match it when your done.

 

i shouldnt have to get a custon chip because of this cam right (above listed) i believe zepher ran it in his 86 transam with the 305tpi and had no problems. when i get the motor apart im going to have the heads rebuilt and ported out also im going to have the bottom intake piece ported and the upper plentum ported. what most of you are saying is with my combo above with no trany or suspension work just all motor i should get low 14's and with trany and suspension mods done low to mid 13's?

 

you need a PI Vig 2800 stall converter, most see a 1/2 sec reduction. your combo seems Ok Im sure a comp cam would get you into the 12s. As for the chip if you cant DIY, Im sure Ed Wright has done a combo just like yours

 

You will need a chip to optimize your setup. It will run, but it won't be anywhere near it's potential without tuning.
