I am about to pull the trigger on the following parts and was wondering if I was missing the mark on any.

The Engine is an LS1 Stock Except 243 Heads. It is going in an Lotus 7 replica road race car. Total weight is around 1450lbs.

Cam: Howards ASA with 113 LSA https://www.howardscams.com/hydrauli...0-7300-howards
Valve Springs: Comp Cams LS6+ https://www.compcams.com/0-580-max-l...retainers.html
Push Rods: Keeping the stock originals
Lifters: while the heads are off switching to ls7 lifters. Any suggestions on an decent budget set?
Intake: Will I benefit much from upgrading from the stock ls1 to LS6?

 

You’re going to trash the motor when you bend a pushrod.

 

If your worried about stress on the valve train and want to keep low lift get something with .550 lift and you can use the blue LS6 springs, it's a cheap effective combo, lots of people do it, I did previously. Although with 243 heads you would get some benefit from even more lift but cost will go up.

 

Oh nearly forgot, 550 lift and designed to use LS6 springs, mine was a BTR truck cam with .551 lift Summit has a whole range of them close to that lift with there new cam line up for LS6 springs. Although the cam I had from Summit .545 lift from memory but measured less when I measured it.
Might as well run the most lift you can safely if you go via that route .550 is safe.

 

Ditch the low lift cam , go with Summit Racing 8707 .... https://www.summitracing.com/parts/sum-8707 or WS6 store ASA high lift can ...... http://www.ws6project.com/user_stor/...oducts_id=8670 and 11/32 PR and some slow leakdown lifters

 

Yes that 8707 cam sounds amazing I nearly bought it just for the idle in video.

 

Your selection will work fine.
It’s a 1450lb car guys. Would haul *** with a stone stock LS1.

The LS6 intake is worth 15hp or so

 

Thanks for all the replies. I will check out the other cam selections. The one thing I liked about the ASA cam was the smooth power and flat torgue curves throughout the entire rpm range I run 2000-6500.

A couple of folks recommended upgrading the pushrods. If I stick with the low lift howards cam and LS6+ springs is that necessary?

Also, forgot that I needed to upgrade the cam sprocket to a 3 bolt version. Is the Cloyes c3210 ok to use? https://www.jegs.com/i/Cloyes/220/C-3210/10002/-1

 

I used the cloyes CS 3220 for my LS1 worked well, I think it was an LS2 chain bit stronger, I bought mine off Amazon .

 

If your only going to rev it to 6500 as you say above (that's what I would do too) then you should get a milder cam the peaks closer to 6000 it will still give a decent increase in power. It will feel incredible in a car that light whatever you do.

 

Shoot, if it were me I’d might even just run a stock LS6 cam in that setup. You’d probably be around 385-390 wheel with the stock LS6 heads and an LS6 manifold. It would absolutely rip in a 1,450 pound vehicle.

 

Unless your set on a choppy idle i would just do an ls6 topend. Great bang for the buck.

 

Yes I agree with TimsLS1 go with CS 3220 over the 3210 .The one he recommended is a great value , not sure I'd order on Amazon thought Iv had alot problems with them .

 

OP, the community has made some great recommendations. The stage 2 Pro LS SUM-8707 would absolutely rip in a combo like yours. The lobes were designed to be very stable and easy on parts at 7000 rpm. It would work well in a road-race application. This would require some .600" lift capable beehives like the TFS-16918-16 springs which currently retail for $161.99.

We understand your trying to save some money on accessory parts needed. For strong power from 2000-6500 and using LS6 springs, we would recommend our stage 3 truck cam SUM-8713. Specs on it are .545"/.545", 222/231, 112+5. It will provide the power right where you're looking for it and be easy to tune. With a light car like yours, it will have a nice steady powerband to 6500. If you’re looking for something sized similar to the ASA cam, the stage 4 truck cam SUM-8714 would be a great choice. Specs on it are .545"/.545", 226/230, 112+4. It has a slightly more aggressive idle and the powerband climbs to 6800. Either of these pair well with the budget-friendly LS6 springs NAL-12499224. These springs currently retail for $85.62.

Keeping budget in mind. All three of our cams mentioned currently retail for $289.99 compared to the Howard's at $351.99.

As for pushrods, the common Chromoly 5/16" .080" wall $100 or less pushrod set would be great insurance for valvetrain stability. Likely a 7.400" would be the ticket for .545" lift. 7.425" is a little more common for .600" lift. As always you should measure for correct pushrod length.

We have you covered on the LS7 lifters with our SUM-HT214. These are also available in a kit with new trays and bolts SUM-HTLSKIT. The LS2 timing chain is what we include in our CMB-09-0029 cam change kit.

Something to think about for down the road is a better intake. The Dorman LS2 intake RNB-615-901 is a great deal and will outpower the LS1, LS6, and many aftermarket intakes.

Anything else that you may need we likely have it. We have a saying "we have everything you need for anything you drive" and we mean it.

 

That cam/spring combo isn't going to bend the stock pushrods.

 

That cam will be fine for what you are doing. I've seen pushrods bent in stock 6 speed cars and have seen valve springs fail in stock vehicles of all kind trucks/cars.
look at the PSI 1511 springs . Just my 2 cents put pushrods and better springs in it . It's cheap insurance.

 

The 8713 or 8714 are your best options for power and durability in my eyes

Our high lift asa cam is far superior to either of those and still use a pac beehive spring.
Ls1 with milled 243s unported and full exhaust on here made 430/420. Thats the 110lsa. We have a 115 lsa also for boost or quieter sound etc.
