Former Ford owner need Chevy tips..

[WICKED]

Here is my scenario:

What I have:
Chevy 1988 350 block low miles, all stock.
TH350 trans
3.73 final drive ratio in a 2700 lb car.

What I need:
What Heads, cam intake stall speed should I go with for a fun street/strip car with emphasis on 1/4 mile times?

This of course will be done with used budget parts, nothign fancy.I have a line on some 305 TPI heads ( to raise compression) that I can get for free, they are pocket ported with stock valve train. Don;t knwo if this is what I shoudl do or not.

I was thinking of a 2200-2500 stall maybe higher all depends on what Cam I choose. HELP!

Get a set of vortec heads [Sorry I sold my last set will get more soon?] Pocket port 64 cc chambers should be around 9.4 compression easy on good gas. Put no more then 32-34 degrees into it will work just fine. Cam choice would be a hyd roller if you have the block to do it [ MAX ] rework heads to handle 550 lift comp cam XR282HR cam call for 2000+ converter Tim runs 12.36 in a pontiac lemans with a 4:11 gear. In a 2700 lb car should go high 11s with a good tune. [ Cheap ] vortec heads pocket port stock springs will handle 480 lift use comp EX268H hydraulic cam can use stock heads no work and springs. Fine a VAGA 10 converter for the fine spline th350 and your set, motor will make around 400 HP. should run mid 12s in 2700 lb car cheap set up under $500 heads cam and converter might want to go through bottom end of motor and a hone and rings. need help call 920-901-9777 Good Choice going with a SBC What have you got that weights 2700 lbs VAGA, GREMLEN ?????

so the vortec heads work well? The TPI heads will increase port velocity a ton though. Since I am not reving theis thing past 5800 RPM, port velocity will net excellent throttle response and low to mid range torque!

the swirl port heads are some of teh shittiest head the General ever made. Vortec's are the best bang for the buck

If you look in side the port you will see a ramp takes up half of the port. Runs good to 3800. The vortecs are worth 25-30 hp with out any porting. Needs work on the exhaust side. Put those heads on the scrap pile. Even a set of 882, 624, 441 any thing but those heads will flow more. Only problem there 74-76cc chambers no compression. Do the vortecs and you will be a lot happer. I like your IDEA for a car. I know Carl ran 12.50 with the cheap vortec in a S-10 and its about 200 lb heaver then you are. might go 12.30 in a 2700 bemer.

[WICKED]

damn that would be fun, look slike I will be looking for a set of vortec heads then.. now what about for a cam? I like COmp cams, and the 268 grinds as mentioned probably woudl work great huh? What carbed intake works well on a SBC?

[bohn]

I run a set of vortec heads by pro-topline, there suppose to flow alittle better than the GM ones and they have screw in studs and are good to 560 lift. I bought them brand new from comp in oshkosh for $550 the pair. The stock GM heads are only good to 480lift. I would just get a set from comp or scoggin dickey for around $600 and already set-up for big lift. You can find a set used for around $300, but your gonna stick another $300 in them to freshen them up and get the lift you want.

Lots of people use the XE274 comp cam, seems to work good with the vortec head. I'd just call comp cams on a recommendation.

Remember too that vortec heads require a different intake than a standard SBC, They make a wide variety though.

[Slow Ride]

If you really want to get the most out of it run a roller cam. That '88 block is machined for them. Call up Comp Cams and ask what they recommend. With that light of a car you can get a little more hairy with the cam. I'd say a XR288HR for a hyd roller with a Victory Jr. intake. I'm guessing you'll probably want to spray it too right??? Then you might want to try the NX288HR cam and a small shot. get at least a 3000 stall and run faster than your old stang did.

[bohn]

Or you can just buy my motor, so i can buy a ford !!!!

Of course I will spray a 150 shot at it :) I don;t forsee the rear diff holding up very long, but they can easily be swapped out in an hour and a half.

You guys think this will be faster then my old stang? I don't know.. its tough to say until its all together.. I doubt a mild SBC like this with a 150 shot will run 10's...

[lazyass]

gut it enough and it will probally be close to breaking into the ten's

[YAV8]

Don't sell the SBC short. With the [as you put it] mild motor with some head work and right cam will make a easy 470+++HP and 150 of snot around 600+ and 2700lbs your right you will not run 10s You will break shit in the back. Call currie and order a 9 inch. Put in the bars because you will need them to go that fast. You might want to put in some better pistons those used cast ones, they might not live real long with snot. With that SBC in the frame rails the motor combination are end less. 383 394 400 406 421 434 454 hell low 10s you could do that on pump gas pulling a trailer with your mustang on it and no snot. Welcome to the land of the SBC.

[WICKED]

yeah I am seeing that there are alot of options. I can get a complete eagle rotating assembly, with cast crank, rods, forged pistons ( 11.1 compr with 76 cc heads) waveloc bolts etc etc.. for $389 my cost.

[WICKED]

oh an dI am just lookign for a fun , odd differnt then what everyone has street car..

[bohn]

I think a SBC or SBF would be cool in a beamer...i've always wanted to do and older Z car with a SB in it.

[jdsgallops]

Sell the GM stuff to one of these guys and build an aluminum headed 302 Ford that will drop the weight another 100-150lbs and make the same HP as that SBC. That is what any good smart Ford owner would do.

[lazyass]

hmm

[El nino]

buy brommos motor n you go hella fast ...
