gt40p heads hmmmmm

[zoomie]

ok i suppose this has been discussed before, but i thought it would be a good idea to see what you guys think.

im using a HO motor with explorer intake and gt40p heads, beehive springs and hardend rods.

the idea was to obtain a set of gt40p heads mill them .010, blend the bowls and port match, poss have bigger valves put in???? talked to the machine shop guy , and hes said he could put chevy valves in 1.94 1.60. is it worth it to do this or should i just leavem alone? with the 35-510-8 XE258 cam he said it was pushing something in the area of 380 hp and close to that in tq on camquest?

I know porting with these are tricky and probably best thing to do is just get the bowel work done. but before i go spend like 400 bucks into these i want to make sure of what the best idea would to be. thoughts and discuss thanks!

honestly with the cost of the heads and quality work done to em.....id rather get a set of Trickflow or AFR heads that already have the bogger ports and valves with much more upside and are lighter

price would be suprisingly similar if u do the research

If you end up going that route, skip going with the larger valves.

agreed. velocity is key with these heads. they respond well to bowl work, angled valves, and milling. but larger valves and larger ports dont do much.

Yeah if you look on corral.net you can find some good deals on TFS or AFR heads over there. I've seen them go for a 1000 or less, it might be worth going with those instead of putting money into the gt40ps...

working on a shoe string budget here guys i only have 1000 to work with ...maybe, however thank you for the inputs though. if anyone feels like donating to the race box feel free to PM me lol

 

[The Bone]

for that budget get some edelbrock aluminums
seriously

 

[dsblk93gt]

New Edelbrock E-Streets for $899 most anywhere....same as a Performer just different springs

 

[AdirondackFox08]

^Really? I didn't know that.

 

[dsblk93gt]

This is what I have heard, none of Edelbrocks info states this.

oook perhpas ill clarify a little bit more my budget for this year is about 1000 total, so in other words i have to get the heads, cam, rocker arms, springs, rods, tires, interior, front end upgrades, poly bushings, shocks, primer, more paint if i need it, materials for custom subwoofer box and other small items and so forth. to help me out i get alot of this stuff for fairly decent pricing. the heads are 65 bucks, i can pick up gt40 explorer intakes for about 15-25 bucks, XE258 cam i found for 180 some guy has it in his closet new, im doing th ebest i can to build a nice DD but also be able to go down the track at a decent clip .

XE258 is a nice cam but you cannot run it with GT40P heads without some real good valve springs due to the high lift. I guess if on a super tight budget and the heads are in decent shape, maybe just take the valves out clean everything up, new spring kit, and install you may be ok.

i know read first post.... running beehive springs, probably comp cam ones at that lol
valves will come out, just will be blending bowls and minor clean up of the heads, heads will be milled .010 ,guy at machine shop cuts me a decent deal.

 

[The Bone]

youll never do all that for 1000

 

[dsblk93gt]

Yea, that is not very realistic. I'd pick one area to work on and do it right, your spreading the $ to thin to do all that work.

 

[AdirondackFox08]

Yeah I agree with the last two posts. I know you probably don't want to hear it but you should save your money. Why don't you put the money towards some handling aspects, or your interior... You don't want to skimp on your hci package or you may not be happy with it, imo.

 

[zoomie]

well i suppose 1000 might be a little unrealistic, but it wont be far off, ill be busting my hump to get anything else i need for the car, i have had this for 2 yrs now and each year it gets better and better, it not easy, but, it also helps when I can do most of if not all of the work. although i do have help from time to time. you guys have been awsome in the advice dept. this year is going to be interesting for sure!
